Although originally developed by\nLudvig Strigeus\n, since December 7, 2006, the code is owned and maintained by\nBitTorrent, Inc\n.\n[\n12\n]\nThe code has also been employed by BitTorrent, Inc. as the basis for version 6.0 and above of the\nBitTorrent client\n, a re-branded version of μTorrent. All versions are written in\nC++\n.\n[\n5\n]\nOut of general discontent with\nbloatware\n, Serge Paquet suggested to\nLudvig Strigeus\nthat he should make a smaller and more efficient BitTorrent client. Strigeus began to conceptualize the plans for the program's development, which, at the time, did not include making the client feature-rich. After initially working on it for about a month during the last quarter of 2004 (the first build is dated October 17, 2004), mostly during his free time before and after work, Strigeus ceased coding μTorrent for a year. He resumed work on September 15, 2005, and three days later, the first public release (version 1.1 beta) was made available as\nfree software\n, and began generating feedback.\nOn March 4, 2006, PeerFactor SARL announced the signing of a six-month contract with Strigeus for the development of \"new content distribution applications on the Web\".\n[\n13\n]\nPeerFactor SARL was a relatively new company formed by former employees of PeerFactor, which was a subsidiary of the French anti-piracy organization\nRetspan\n.\nStrigeus stated that his coding for PeerFactor SARL was to use his expertise in the optimization of the BitTorrent\nprotocol\nto create a\n.dll\nwhich PeerFactor SARL intended to use as part of a distribution platform for files in a corporate setting.\n[\n14\n]\nAt the time there was some speculation that μTorrent may have been modified to spy on users on Peerfactor's behalf,\n[\n13\n]\n[\n15\n]\nhowever to date (even following μTorrent's acquisition by BitTorrent, Inc.) no evidence has been produced to support these allegations.\nOn December 7, 2006, μTorrent was purchased by\nBitTorrent, Inc.\n[\n12\n]\nIt was later announced that BitTorrent paid an undisclosed amount to\nSpotify\nfor this purchase, the then owner of the software.\n[\n16\n]\nOn September 18, 2007,\nBitTorrent\n6.0 was released. Although previous versions of the BitTorrent client had been\nopen source software\n, with version 6 it became proprietary.\nIn April 2017, BitTorrent founder\nBram Cohen\nannounced that the next version of μTorrent would be\nweb browser\nbased. This μTorrent version allows users to stream torrents from the default web browser, similar to a regular\nstreaming site\n.\n[\n17\n]\nFeatures present in μTorrent include:\nMagnet Links\n(URIs), added in version 1.8, released on August 9, 2008.\n[\n18\n]\nTeredo tunneling\n\/\nIPv6\nsupport\nMicro Transport Protocol\n(μTP) preliminary support as of 1.8.2 with full-support added in 2.0\nUPnP\nsupport for all versions of Windows, without needing\nWindows XP\n's UPnP\nframework\nProtocol encryption\n(PE)\nPeer exchange\n(PEX) with other BitTorrent clients:\nlibtorrent\nand clients based on it like\nDeluge\nor\nqBittorrent\nhave full μTorrent PEX support\nTransmission\nand clients based on libTransmission have full μTorrent PEX support\nKTorrent\nhas full μTorrent PEX support as of 2.1 RC1\nVuze\n, formerly Azureus, has full support as of version 3.0.4.3\nRSS\n(\"\nbroadcatching\n\")\n\"\nTrackerless\n\" BitTorrent support using\nDHT\n, compatible with the original\nBitTorrent client\nand\nBitComet\nUser configurable intelligent disk\ncaching\nsystem\nFull proxy server\nsupport\nHTTPS\ntracker support\nConfigurable\nbandwidth\nscheduler\nLocalized\nfor 67 languages.\n[\n19\n]\nInitial seeding\nof torrents\nCustomizable\nsearch bar\n& user interface design.\n[\n20\n]\nConfiguration settings and temporary files are stored in a single directory, allowing portable use\nWebUI\n: A\nplugin\ncurrently in\nbeta testing\nthat allows μTorrent running on one computer to be controlled from another computer, either across the internet or on a\nLAN\n, using a\nWeb browser\nEmbedded Tracker\n: a simple tracker designed for seeding torrents, lacking a web interface or list of hosted torrents. It is not designed for secure or large-scale application.\n[\n21\n]\nQuick-resumes interrupted transfers\nTwo\n\"easter eggs\"\nin the About subsection of Help: clicking the μTorrent logo plays a\nDeep Note\n-like sound effect, and typing the letter \"t\" starts a\nTetris\n-like game called μTris,\n[\n22\n]\n[\n23\n]\n[\n24\n]\nwhich in 2008 was selected as #1 of the \"Top 10 Software Easter Eggs\" by\nLifeHacker\n.\n[\n25\n]\nThe ability to use encryption of all traffic to bypass torrent blocking on the network.\n[\n26\n]\nμTorrent is shipped as a single stand-alone\ncompressed executable\nfile, installed at first run. Recent versions have included the ability to install themselves on first run. Small executable size is achieved by avoiding the use of many\nlibraries\n, notably the\nC++ standard library\nand\nstream facilities\n, and creating substitutes written specifically for the program. The executable is then compressed to roughly half of its compiled and linked size using\nUPX\n.\nOperating system support\n[\nedit\n]\nScreenshot of the macOS version of μTorrent (up to 0.9.2)\nμTorrent is available for\nMicrosoft Windows\n,\nmacOS\n, and\nAndroid\n.\n[\n6\n]\n[\n27\n]\nA\nμTorrent Server\nis also available for\nLinux\n.\n[\n28\n]\nCurrently, μTorrent supports\nWindows XP\nor later,\nMac OS X Snow Leopard\nor later, and\nAndroid 5.0\nor later.\n[\n27\n]\nThe latest version for Windows XP is 3.5.5 build 45311 Stable\n[\n29\n]\n[\n30\n]\ndated July 22, 2019.\n[\n31\n]\nHowever, the official termination of support for Windows XP has not been reported. On the official website of the program, this operating system is still listed as supported.\n[\n32\n]\nThe first test version for macOS, running on\nMac OS X Leopard\n, was released on 27 November 2008.\n[\n33\n]\nOn September 2, 2010, the native\nLinux\nversion of μTorrent Server was released. Firon, an administrator of the μTorrent community forum, said that they had been working on this project for a few months prior to the release as it was the most requested feature for some time. This release is intended for users who are seeking a fast\ncommand-line interface\nbased\nBitTorrent\nclient with a remote web-based management. They also mentioned that a full featured client with a\nGUI\nis a work in progress.\n[\n34\n]\nAs of 2020, μTorrent server for Linux supports\nDebian\n6.0 or later and\nUbuntu\n12 or later, with both 32-bit & 64-bit options available.\n[\n35\n]\nOn August 1, 2019, μTorrent announced that users who upgrade to\nmacOS Catalina\nwill be upgraded to μTorrent web automatically since that version of macOS (and subsequent releases) supports 64-bit applications only.\n[\n36\n]\nIn early versions by Strigeus, μTorrent displayed advertisements in a frame on the web browser by a built-in web redirection via nanotorrent for search queries entered through the search bar. Some users thought this suspicious because\nIP address\ntracking could be implemented by recording which machine was downloading\/receiving the advertisements, and user-query tracking could easily be done through whichever web interface the client was using. After a short time, that method of advertising was disabled, mitigating those concerns.\n[\n37\n]\nA later version of the software displays advertisements (server-side) in a frame at the top of the browser each time the \"search all sites\" function is used. In version 1.5, no ads are present in the program itself.\nAs of build 463, a redirect bypass feature became available in the Advanced options.\nAs of version 1.8.2, the μTorrent installer downloads and installs the\nAsk.com toolbar\non the first run of the program; the user can opt out of installing that toolbar by deselecting it before allowing the μTorrent installation to proceed.\n[\n38\n]\n[\n39\n]\nThe developers stated the addition was needed for funds to continue development. In late 2010, the Ask.com toolbar was replaced with the\nConduit Engine\n.\nCurrently, μTorrent generates revenue through in-content advertisements (in the free version for Windows) and the \"pro\" version, which is available in 3 bundles (available for both classic & web client for Windows).\n[\n40\n]\nIn late 2010, some controversy arose with the release of μTorrent which included\nadware\nin the form of the\nConduit\nEngine, which installed a toolbar, and made homepage and default search engine changes to a user's web browser. A number of users reported that the installation was made without the user's consent.\n[\n41\n]\nThere were some complaints that the adware software was difficult to remove.\n[\n42\n]\nIn 2011, μTorrent bundled the\nBing Toolbar\n.\n[\n43\n]\nOn July 15, 2011, BitTorrent announced that they would offer a paid version of μTorrent called \"μTorrent Plus\". This new version would offer extra features, such as integrated file conversion, anti-virus, and a built-in media player.\n[\n44\n]\nOn 6 October 2011, the\nPre-alpha\nof μTorrent Plus was released to an invitation-only community.\n[\n45\n]\nAs of December 2011, μTorrentPlus 3.1 was available for $24.95; as of December 2014, the Plus version was available as a $19.95 yearly subscription.\nIn August 2012, BitTorrent announced the addition of\nadvertising\nin the free version of μTorrent; each ad could only be dismissed after the user had viewed it.\n[\n46\n]\nDue to response from users, a few days later, the company stated that ads could be optionally turned off.\n[\n47\n]\nA user-created tool known as \"Pimp My μTorrent\" was also created to simplify the process of disabling ads in the Windows version.\n[\n48\n]\nStarting with μTorrent version 3.2.2, the software also contains in-content advertisements described as \"Featured Torrent\".\n[\n49\n]\nAs with the other ads, it is possible to disable this content.\n[\n49\n]\nIn March 2015, μTorrent began automatically installing a background application called Epic Scale to mine\ncryptocurrency\nfor the benefit of BitTorrent, Inc., while allegedly giving a portion to charity.\n[\n50\n]\nEpic Scale mines\nLitecoin\nusing both\nCPU\nand\nGPU\npower, and is classified as \"\nriskware\n\" by some security programs. A μTorrent developer disputed whether the automatic installation was really automatic, and claimed that as with all other \"partner\" programs bundled with the software, users could decline the installation.\n[\n51\n]\n[\n52\n]\n[\n53\n]\nOn 28 March, Epic Scale was removed from the installation and dropped from the list of software bundle partners.\n[\n54\n]\nBeginning in 2018, advertisements for\nYandex Browser\nand other Yandex-produced software were included in Russian and Ukrainian versions of μTorrent.\n[\n55\n]\nIn 2005, an\nadmin\non the μTorrent forums wrote: \"I don't really know how it's pronounced, I usually say 'you torrent' because it looks like a u\". While stating they were not sure, they mentioned that the correct pronunciations for \"μTorrent\" could be \"microtorrent\", \"mytorrent\" (as \"my\"\n[myː]\nis the Swedish pronunciation of the Greek letter μ) and \"mutorrent\".\n[\n56\n]\nIn Greece, where the software was widely used, it is called\nme torrent\n,\n[\ncitation needed\n]\nsince the letter μ of the Greek Alphabet is pronounced mi in modern Greek.\n[\n57\n]\nThe symbol μ is the lowercase\nGreek\nletter\nmu\n, which stands for the\nSI prefix\n\"\nmicro-\n\".  It refers to the program's originally small footprint.\n[\ncitation needed\n]\nμTorrent was created and initially developed by\nLudvig Strigeus\n(\"ludde\", from\nSweden\n). Serge Paquet (\"vurlix\", from\nCanada\n) acted as release coordinator, and had intended to work on porting the software to Linux and macOS. He maintained the μTorrent website and forum until the end of 2005 but is no longer affiliated with μTorrent.\nSince its purchase in 2006, development has been performed by various employees of Bittorrent Inc.; Strigeus is no longer affiliated with μTorrent.\nThis section's\nfactual accuracy\nmay be compromised due to out-of-date information\n.\nPlease help update this article to reflect recent events or newly available information.\n(\nFebruary 2026\n)\nμTorrent has been praised for its small size and minimal computer resources used, which set it apart from other clients.\nPC Magazine\nstated that it \"packs an outstanding array of features\" in 2006\n[\n58\n]\nand listed it in their 2008 \"Best free 157 software tools\".\n[\n59\n]\nIt was also in\nPC World\n's \"101 Fantastic freebies\".\n[\n60\n]\nThe website\nTorrentFreak\n.com said it was the most feature rich BitTorrent client available,\n[\n61\n]\nlater summarizing a 2009\nUniversity of California, Riverside\nstudy\n[\n62\n]\nwhich concluded that \"μTorrent Download Speeds Beat Vuze By 16%\" on average and \"on 10% of [the 30 most used] ISPs, μTorrent users were downloading 30% faster than Vuze users\".\n[\n63\n]\nAbout.com\nsaid it was the best BitTorrent client available, citing its small size and \"minimal impact to the rest of your computer's speed.\"\n[\n64\n]\nWired.com\nsaid its \"memory footprint is also ridiculously small\".\n[\n65\n]\nPC & Tech Authority\nmagazine (Australia) gave it 6 stars (out of 6).\n[\n66\n]\nLifehacker.com\nrated it the best BitTorrent client available (Windows) in 2008,\n[\n67\n]\n2011 (Windows\n[\n68\n]\nand Mac\n[\n69\n]\n) and a follow-up user poll rated it the most popular torrent client in 2015.\n[\n70\n]\nCNET\n.com gave it 5 stars (of 5) saying it features \"light and quick downloading\".\n[\n71\n]\nIn November 2009, 52 million users were reported to be using the application,\n[\n72\n]\nand in late 2011, 132 million.\n[\n73\n]\nAccording to a study by\nArbor Networks\n, the 2008 adoption of\nIPv6\nby μTorrent caused a 15-fold increase in IPv6 traffic across the Internet over a ten-month period.\n[\n74\n]\nComparison of BitTorrent clients\n^\n\"uTorrent 3.6.0 For Windows (build 46590)\"\n.\nµTorrent blog\n. 22 November 2022\n.

Strigeus began to conceptualize the plans for the program's development, which, at the time, did not include making the client feature-rich. After initially working on it for about a month during the last quarter of 2004 (the first build is dated October 17, 2004), mostly during his free time before and after work, Strigeus ceased coding μTorrent for a year. He resumed work on September 15, 2005, and three days later, the first public release (version 1.1 beta) was made available as [free software](https:\/\/en.wikipedia.org\/wiki\/Free_software \"Free software\"), and began generating feedback.\n\n### PeerFactor SARL\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=%CE%9CTorrent&action=edit&section=3 \"Edit section: PeerFactor SARL\")\\]\n\nOn March 4, 2006, PeerFactor SARL announced the signing of a six-month contract with Strigeus for the development of \"new content distribution applications on the Web\".[\\[13\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-slickpeerfactorSARL-13) PeerFactor SARL was a relatively new company formed by former employees of PeerFactor, which was a subsidiary of the French anti-piracy organization [Retspan](https:\/\/en.wikipedia.org\/wiki\/Retspan \"Retspan\").\n\nStrigeus stated that his coding for PeerFactor SARL was to use his expertise in the optimization of the BitTorrent [protocol](https:\/\/en.wikipedia.org\/wiki\/Protocol_\$computing\$ \"Protocol (computing)\") to create a [.dll](https:\/\/en.wikipedia.org\/wiki\/Dynamic-link_library \"Dynamic-link library\") which PeerFactor SARL intended to use as part of a distribution platform for files in a corporate setting.[\\[14\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-14) At the time there was some speculation that μTorrent may have been modified to spy on users on Peerfactor's behalf,[\\[13\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-slickpeerfactorSARL-13)[\\[15\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-15) however to date (even following μTorrent's acquisition by BitTorrent, Inc.) no evidence has been produced to support these allegations.\n\n### Ownership change\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=%CE%9CTorrent&action=edit&section=4 \"Edit section: Ownership change\")\\]\n\nOn December 7, 2006, μTorrent was purchased by [BitTorrent, Inc.](https:\/\/en.wikipedia.org\/wiki\/BitTorrent_\$company\$ \"BitTorrent (company)\")[\\[12\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-purchase-12) It was later announced that BitTorrent paid an undisclosed amount to [Spotify](https:\/\/en.wikipedia.org\/wiki\/Spotify \"Spotify\") for this purchase, the then owner of the software.[\\[16\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-16)\n\nOn September 18, 2007, [BitTorrent](https:\/\/en.wikipedia.org\/wiki\/BitTorrent_\$software\$ \"BitTorrent (software)\") 6.0 was released. Although previous versions of the BitTorrent client had been [open source software](https:\/\/en.wikipedia.org\/wiki\/Open_source_software \"Open source software\"), with version 6 it became proprietary.\n\nIn April 2017, BitTorrent founder [Bram Cohen](https:\/\/en.wikipedia.org\/wiki\/Bram_Cohen \"Bram Cohen\") announced that the next version of μTorrent would be [web browser](https:\/\/en.wikipedia.org\/wiki\/Web_browser \"Web browser\") based.

Recent versions have included the ability to install themselves on first run. Small executable size is achieved by avoiding the use of many [libraries](https:\/\/en.wikipedia.org\/wiki\/Library_\$computer_science\$ \"Library (computer science)\"), notably the [C++ standard library](https:\/\/en.wikipedia.org\/wiki\/C%2B%2B_Standard_Library \"C++ Standard Library\") and [stream facilities](https:\/\/en.wikipedia.org\/wiki\/Iostream \"Iostream\"), and creating substitutes written specifically for the program. The executable is then compressed to roughly half of its compiled and linked size using [UPX](https:\/\/en.wikipedia.org\/wiki\/UPX \"UPX\").\n\n### Operating system support\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=%CE%9CTorrent&action=edit&section=7 \"Edit section: Operating system support\")\\]\n\n[![](https:\/\/upload.wikimedia.org\/wikipedia\/en\/thumb\/8\/85\/%CE%9CTorrentMac.png\/250px-%CE%9CTorrentMac.png)](https:\/\/en.wikipedia.org\/wiki\/File:%CE%9CTorrentMac.png)\n\nScreenshot of the macOS version of μTorrent (up to 0.9.2)\n\nμTorrent is available for [Microsoft Windows](https:\/\/en.wikipedia.org\/wiki\/Microsoft_Windows \"Microsoft Windows\"), [macOS](https:\/\/en.wikipedia.org\/wiki\/MacOS \"MacOS\"), and [Android](https:\/\/en.wikipedia.org\/wiki\/Android_\$operating_system\$ \"Android (operating system)\").[\\[6\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-google_play-6)[\\[27\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-Reqs-27) A **μTorrent Server** is also available for [Linux](https:\/\/en.wikipedia.org\/wiki\/Linux \"Linux\").[\\[28\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-Linux-28) Currently, μTorrent supports [Windows XP](https:\/\/en.wikipedia.org\/wiki\/Windows_XP \"Windows XP\") or later, [Mac OS X Snow Leopard](https:\/\/en.wikipedia.org\/wiki\/Mac_OS_X_Snow_Leopard \"Mac OS X Snow Leopard\") or later, and [Android 5.0](https:\/\/en.wikipedia.org\/wiki\/Android_Lollipop \"Android Lollipop\") or later.[\\[27\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-Reqs-27) The latest version for Windows XP is 3.5.5 build 45311 Stable[\\[29\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-29)[\\[30\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-30) dated July 22, 2019.[\\[31\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-31) However, the official termination of support for Windows XP has not been reported. On the official website of the program, this operating system is still listed as supported.[\\[32\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-32)\n\nThe first test version for macOS, running on [Mac OS X Leopard](https:\/\/en.wikipedia.org\/wiki\/Mac_OS_X_Leopard \"Mac OS X Leopard\"), was released on 27 November 2008.[\\[33\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-33)\n\nOn September 2, 2010, the native [Linux](https:\/\/en.wikipedia.org\/wiki\/Linux \"Linux\") version of μTorrent Server was released. Firon, an administrator of the μTorrent community forum, said that they had been working on this project for a few months prior to the release as it was the most requested feature for some time. This release is intended for users who are seeking a fast [command-line interface](https:\/\/en.wikipedia.org\/wiki\/Command-line_interface \"Command-line interface\") based [BitTorrent](https:\/\/en.wikipedia.org\/wiki\/BitTorrent_\$protocol\$ \"BitTorrent (protocol)\") client with a remote web-based management. They also mentioned that a full featured client with a [GUI](https:\/\/en.wikipedia.org\/wiki\/GUI \"GUI\") is a work in progress.[\\[34\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-utorrent1-34)\n\nAs of 2020, μTorrent server for Linux supports [Debian](https:\/\/en.wikipedia.org\/wiki\/Debian \"Debian\") 6.0 or later and [Ubuntu](https:\/\/en.wikipedia.org\/wiki\/Ubuntu \"Ubuntu\") 12 or later, with both 32-bit & 64-bit options available.[\\[35\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-35)\n\nOn August 1, 2019, μTorrent announced that users who upgrade to [macOS Catalina](https:\/\/en.wikipedia.org\/wiki\/MacOS_Catalina \"MacOS Catalina\") will be upgraded to μTorrent web automatically since that version of macOS (and subsequent releases) supports 64-bit applications only.[\\[36\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-36)\n\n## Revenue\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=%CE%9CTorrent&action=edit&section=8 \"Edit section: Revenue\")\\]\n\nIn early versions by Strigeus, μTorrent displayed advertisements in a frame on the web browser by a built-in web redirection via nanotorrent for search queries entered through the search bar. Some users thought this suspicious because [IP address](https:\/\/en.wikipedia.org\/wiki\/IP_address \"IP address\") tracking could be implemented by recording which machine was downloading\/receiving the advertisements, and user-query tracking could easily be done through whichever web interface the client was using. After a short time, that method of advertising was disabled, mitigating those concerns.[\\[37\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-37)\n\nA later version of the software displays advertisements (server-side) in a frame at the top of the browser each time the \"search all sites\" function is used. In version 1.5, no ads are present in the program itself.\n\nAs of build 463, a redirect bypass feature became available in the Advanced options.\n\nAs of version 1.8.2, the μTorrent installer downloads and installs the [Ask.com toolbar](https:\/\/en.wikipedia.org\/wiki\/Ask.com_toolbar \"Ask.com toolbar\") on the first run of the program; the user can opt out of installing that toolbar by deselecting it before allowing the μTorrent installation to proceed.[\\[38\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-38)[\\[39\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-39) The developers stated the addition was needed for funds to continue development. In late 2010, the Ask.com toolbar was replaced with the [Conduit Engine](https:\/\/en.wikipedia.org\/wiki\/Conduit_\$publisher_network_and_platform\$ \"Conduit (publisher network and platform)\").\n\nCurrently, μTorrent generates revenue through in-content advertisements (in the free version for Windows) and the \"pro\" version, which is available in 3 bundles (available for both classic & web client for Windows).[\\[40\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-40)\n\n### Toolbars\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=%CE%9CTorrent&action=edit&section=9 \"Edit section: Toolbars\")\\]\n\nIn late 2010, some controversy arose with the release of μTorrent which included [adware](https:\/\/en.wikipedia.org\/wiki\/Adware \"Adware\") in the form of the [Conduit](https:\/\/en.wikipedia.org\/wiki\/Conduit_\$publisher_network_and_platform\$ \"Conduit (publisher network and platform)\") Engine, which installed a toolbar, and made homepage and default search engine changes to a user's web browser. A number of users reported that the installation was made without the user's consent.[\\[41\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-41) There were some complaints that the adware software was difficult to remove.[\\[42\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-42) In 2011, μTorrent bundled the [Bing Toolbar](https:\/\/en.wikipedia.org\/wiki\/Bing_Toolbar \"Bing Toolbar\").[\\[43\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-43)\n\n### Paid version\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=%CE%9CTorrent&action=edit&section=10 \"Edit section: Paid version\")\\]\n\nOn July 15, 2011, BitTorrent announced that they would offer a paid version of μTorrent called \"μTorrent Plus\". This new version would offer extra features, such as integrated file conversion, anti-virus, and a built-in media player.[\\[44\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-%CE%BCTorrent_plus_announcement-44) On 6 October 2011, the [Pre-alpha](https:\/\/en.wikipedia.org\/wiki\/Pre-alpha \"Pre-alpha\") of μTorrent Plus was released to an invitation-only community.[\\[45\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-%CE%BCTorrent_plus_update-45) As of December 2011, μTorrentPlus 3.1 was available for \\$24.95; as of December 2014, the Plus version was available as a \\$19.95 yearly subscription.\n\n### Ads and malware\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=%CE%9CTorrent&action=edit&section=11 \"Edit section: Ads and malware\")\\]\n\nIn August 2012, BitTorrent announced the addition of [advertising](https:\/\/en.wikipedia.org\/wiki\/Advertising \"Advertising\") in the free version of μTorrent; each ad could only be dismissed after the user had viewed it.[\\[46\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-46) Due to response from users, a few days later, the company stated that ads could be optionally turned off.[\\[47\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-47) A user-created tool known as \"Pimp My μTorrent\" was also created to simplify the process of disabling ads in the Windows version.[\\[48\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-48) Starting with μTorrent version 3.2.2, the software also contains in-content advertisements described as \"Featured Torrent\".[\\[49\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-in-content-ads-49) As with the other ads, it is possible to disable this content.[\\[49\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-in-content-ads-49)\n\nIn March 2015, μTorrent began automatically installing a background application called Epic Scale to mine [cryptocurrency](https:\/\/en.wikipedia.org\/wiki\/Cryptocurrency \"Cryptocurrency\") for the benefit of BitTorrent, Inc., while allegedly giving a portion to charity.[\\[50\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-50) Epic Scale mines [Litecoin](https:\/\/en.wikipedia.org\/wiki\/Litecoin \"Litecoin\") using both [CPU](https:\/\/en.wikipedia.org\/wiki\/CPU \"CPU\") and [GPU](https:\/\/en.wikipedia.org\/wiki\/GPU \"GPU\") power, and is classified as \"[riskware](https:\/\/en.wikipedia.org\/wiki\/Riskware \"Riskware\")\" by some security programs. A μTorrent developer disputed whether the automatic installation was really automatic, and claimed that as with all other \"partner\" programs bundled with the software, users could decline the installation.[\\[51\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-verge-epicscale-51)[\\[52\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-engadget-52)[\\[53\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-torrentfreakriskware-53) On 28 March, Epic Scale was removed from the installation and dropped from the list of software bundle partners.[\\[54\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-54)\n\nBeginning in 2018, advertisements for [Yandex Browser](https:\/\/en.wikipedia.org\/wiki\/Yandex_Browser \"Yandex Browser\") and other Yandex-produced software were included in Russian and Ukrainian versions of μTorrent.[\\[55\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-55)\n\n## Pronunciation\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=%CE%9CTorrent&action=edit&section=12 \"Edit section: Pronunciation\")\\]\n\nIn 2005, an [admin](https:\/\/en.wikipedia.org\/wiki\/Internet_forum#Administrators \"Internet forum\") on the μTorrent forums wrote: \"I don't really know how it's pronounced, I usually say 'you torrent' because it looks like a u\". While stating they were not sure, they mentioned that the correct pronunciations for \"μTorrent\" could be \"microtorrent\", \"mytorrent\" (as \"my\" [\\[myː\\]](https:\/\/en.wikipedia.org\/wiki\/Help:IPA\/Swedish \"Help:IPA\/Swedish\") is the Swedish pronunciation of the Greek letter μ) and \"mutorrent\".[\\[56\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-56) In Greece, where the software was widely used, it is called *me torrent*,\\[*[citation needed](https:\/\/en.wikipedia.org\/wiki\/Wikipedia:Citation_needed \"Wikipedia:Citation needed\")*\\] since the letter μ of the Greek Alphabet is pronounced mi in modern Greek.[\\[57\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-Greek_Alphabet_&_Writing:_An_Introduction-57) The symbol μ is the lowercase [Greek](https:\/\/en.wikipedia.org\/wiki\/Greek_language \"Greek language\") letter [mu](https:\/\/en.wikipedia.org\/wiki\/Mu_\$letter\$ \"Mu (letter)\"), which stands for the [SI prefix](https:\/\/en.wikipedia.org\/wiki\/SI_prefix \"SI prefix\") \"[micro-](https:\/\/en.wikipedia.org\/wiki\/Micro- \"Micro-\")\".

Serge Paquet (\"vurlix\", from [Canada](https:\/\/en.wikipedia.org\/wiki\/Canada \"Canada\")) acted as release coordinator, and had intended to work on porting the software to Linux and macOS. He maintained the μTorrent website and forum until the end of 2005 but is no longer affiliated with μTorrent.\n\nSince its purchase in 2006, development has been performed by various employees of Bittorrent Inc.; Strigeus is no longer affiliated with μTorrent.\n\n## Reception\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=%CE%9CTorrent&action=edit&section=14 \"Edit section: Reception\")\\]\n\n|   |   |\n|---|---|\n| ![](https:\/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/5\/53\/Ambox_current_red_Americas.svg\/60px-Ambox_current_red_Americas.svg.png) | This section's **[factual accuracy](https:\/\/en.wikipedia.org\/wiki\/Wikipedia:Accuracy_dispute \"Wikipedia:Accuracy dispute\") may be compromised due to out-of-date information**.

Although originally developed by [Ludvig Strigeus](https:\/\/en.wikipedia.org\/wiki\/Ludvig_Strigeus \"Ludvig Strigeus\"), since December 7, 2006, the code is owned and maintained by [BitTorrent, Inc](https:\/\/en.wikipedia.org\/wiki\/Rainberry,_Inc. \"Rainberry, Inc.\").[\\[12\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-purchase-12) The code has also been employed by BitTorrent, Inc. as the basis for version 6.0 and above of the [BitTorrent client](https:\/\/en.wikipedia.org\/wiki\/BitTorrent_\$software\$ \"BitTorrent (software)\"), a re-branded version of μTorrent. All versions are written in [C++](https:\/\/en.wikipedia.org\/wiki\/C%2B%2B \"C++\").[\\[5\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-C++-5)\n\nOut of general discontent with [bloatware](https:\/\/en.wikipedia.org\/wiki\/Bloatware \"Bloatware\"), Serge Paquet suggested to [Ludvig Strigeus](https:\/\/en.wikipedia.org\/wiki\/Ludvig_Strigeus \"Ludvig Strigeus\") that he should make a smaller and more efficient BitTorrent client. Strigeus began to conceptualize the plans for the program's development, which, at the time, did not include making the client feature-rich. After initially working on it for about a month during the last quarter of 2004 (the first build is dated October 17, 2004), mostly during his free time before and after work, Strigeus ceased coding μTorrent for a year. He resumed work on September 15, 2005, and three days later, the first public release (version 1.1 beta) was made available as [free software](https:\/\/en.wikipedia.org\/wiki\/Free_software \"Free software\"), and began generating feedback.\n\nOn March 4, 2006, PeerFactor SARL announced the signing of a six-month contract with Strigeus for the development of \"new content distribution applications on the Web\".[\\[13\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-slickpeerfactorSARL-13) PeerFactor SARL was a relatively new company formed by former employees of PeerFactor, which was a subsidiary of the French anti-piracy organization [Retspan](https:\/\/en.wikipedia.org\/wiki\/Retspan \"Retspan\").\n\nStrigeus stated that his coding for PeerFactor SARL was to use his expertise in the optimization of the BitTorrent [protocol](https:\/\/en.wikipedia.org\/wiki\/Protocol_\$computing\$ \"Protocol (computing)\") to create a [.dll](https:\/\/en.wikipedia.org\/wiki\/Dynamic-link_library \"Dynamic-link library\") which PeerFactor SARL intended to use as part of a distribution platform for files in a corporate setting.[\\[14\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-14) At the time there was some speculation that μTorrent may have been modified to spy on users on Peerfactor's behalf,[\\[13\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-slickpeerfactorSARL-13)[\\[15\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-15) however to date (even following μTorrent's acquisition by BitTorrent, Inc.) no evidence has been produced to support these allegations.\n\nOn December 7, 2006, μTorrent was purchased by [BitTorrent, Inc.](https:\/\/en.wikipedia.org\/wiki\/BitTorrent_\$company\$ \"BitTorrent (company)\")[\\[12\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-purchase-12) It was later announced that BitTorrent paid an undisclosed amount to [Spotify](https:\/\/en.wikipedia.org\/wiki\/Spotify \"Spotify\") for this purchase, the then owner of the software.[\\[16\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-16)\n\nOn September 18, 2007, [BitTorrent](https:\/\/en.wikipedia.org\/wiki\/BitTorrent_\$software\$ \"BitTorrent (software)\") 6.0 was released.

Firon, an administrator of the μTorrent community forum, said that they had been working on this project for a few months prior to the release as it was the most requested feature for some time. This release is intended for users who are seeking a fast [command-line interface](https:\/\/en.wikipedia.org\/wiki\/Command-line_interface \"Command-line interface\") based [BitTorrent](https:\/\/en.wikipedia.org\/wiki\/BitTorrent_\$protocol\$ \"BitTorrent (protocol)\") client with a remote web-based management. They also mentioned that a full featured client with a [GUI](https:\/\/en.wikipedia.org\/wiki\/GUI \"GUI\") is a work in progress.[\\[34\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-utorrent1-34)\n\nAs of 2020, μTorrent server for Linux supports [Debian](https:\/\/en.wikipedia.org\/wiki\/Debian \"Debian\") 6.0 or later and [Ubuntu](https:\/\/en.wikipedia.org\/wiki\/Ubuntu \"Ubuntu\") 12 or later, with both 32-bit & 64-bit options available.[\\[35\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-35)\n\nOn August 1, 2019, μTorrent announced that users who upgrade to [macOS Catalina](https:\/\/en.wikipedia.org\/wiki\/MacOS_Catalina \"MacOS Catalina\") will be upgraded to μTorrent web automatically since that version of macOS (and subsequent releases) supports 64-bit applications only.[\\[36\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-36)\n\nIn early versions by Strigeus, μTorrent displayed advertisements in a frame on the web browser by a built-in web redirection via nanotorrent for search queries entered through the search bar. Some users thought this suspicious because [IP address](https:\/\/en.wikipedia.org\/wiki\/IP_address \"IP address\") tracking could be implemented by recording which machine was downloading\/receiving the advertisements, and user-query tracking could easily be done through whichever web interface the client was using. After a short time, that method of advertising was disabled, mitigating those concerns.[\\[37\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-37)\n\nA later version of the software displays advertisements (server-side) in a frame at the top of the browser each time the \"search all sites\" function is used. In version 1.5, no ads are present in the program itself.\n\nAs of build 463, a redirect bypass feature became available in the Advanced options.\n\nAs of version 1.8.2, the μTorrent installer downloads and installs the [Ask.com toolbar](https:\/\/en.wikipedia.org\/wiki\/Ask.com_toolbar \"Ask.com toolbar\") on the first run of the program; the user can opt out of installing that toolbar by deselecting it before allowing the μTorrent installation to proceed.[\\[38\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-38)[\\[39\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-39) The developers stated the addition was needed for funds to continue development. In late 2010, the Ask.com toolbar was replaced with the [Conduit Engine](https:\/\/en.wikipedia.org\/wiki\/Conduit_\$publisher_network_and_platform\$ \"Conduit (publisher network and platform)\").\n\nCurrently, μTorrent generates revenue through in-content advertisements (in the free version for Windows) and the \"pro\" version, which is available in 3 bundles (available for both classic & web client for Windows).[\\[40\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-40)\n\nIn late 2010, some controversy arose with the release of μTorrent which included [adware](https:\/\/en.wikipedia.org\/wiki\/Adware \"Adware\") in the form of the [Conduit](https:\/\/en.wikipedia.org\/wiki\/Conduit_\$publisher_network_and_platform\$ \"Conduit (publisher network and platform)\") Engine, which installed a toolbar, and made homepage and default search engine changes to a user's web browser. A number of users reported that the installation was made without the user's consent.[\\[41\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-41) There were some complaints that the adware software was difficult to remove.[\\[42\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-42) In 2011, μTorrent bundled the [Bing Toolbar](https:\/\/en.wikipedia.org\/wiki\/Bing_Toolbar \"Bing Toolbar\").[\\[43\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-43)\n\nOn July 15, 2011, BitTorrent announced that they would offer a paid version of μTorrent called \"μTorrent Plus\". This new version would offer extra features, such as integrated file conversion, anti-virus, and a built-in media player.[\\[44\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-%CE%BCTorrent_plus_announcement-44) On 6 October 2011, the [Pre-alpha](https:\/\/en.wikipedia.org\/wiki\/Pre-alpha \"Pre-alpha\") of μTorrent Plus was released to an invitation-only community.[\\[45\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-%CE%BCTorrent_plus_update-45) As of December 2011, μTorrentPlus 3.1 was available for \\$24.95; as of December 2014, the Plus version was available as a \\$19.95 yearly subscription.\n\nIn August 2012, BitTorrent announced the addition of [advertising](https:\/\/en.wikipedia.org\/wiki\/Advertising \"Advertising\") in the free version of μTorrent; each ad could only be dismissed after the user had viewed it.[\\[46\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-46) Due to response from users, a few days later, the company stated that ads could be optionally turned off.[\\[47\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-47) A user-created tool known as \"Pimp My μTorrent\" was also created to simplify the process of disabling ads in the Windows version.[\\[48\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-48) Starting with μTorrent version 3.2.2, the software also contains in-content advertisements described as \"Featured Torrent\".[\\[49\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-in-content-ads-49) As with the other ads, it is possible to disable this content.[\\[49\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-in-content-ads-49)\n\nIn March 2015, μTorrent began automatically installing a background application called Epic Scale to mine [cryptocurrency](https:\/\/en.wikipedia.org\/wiki\/Cryptocurrency \"Cryptocurrency\") for the benefit of BitTorrent, Inc., while allegedly giving a portion to charity.[\\[50\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-50) Epic Scale mines [Litecoin](https:\/\/en.wikipedia.org\/wiki\/Litecoin \"Litecoin\") using both [CPU](https:\/\/en.wikipedia.org\/wiki\/CPU \"CPU\") and [GPU](https:\/\/en.wikipedia.org\/wiki\/GPU \"GPU\") power, and is classified as \"[riskware](https:\/\/en.wikipedia.org\/wiki\/Riskware \"Riskware\")\" by some security programs. A μTorrent developer disputed whether the automatic installation was really automatic, and claimed that as with all other \"partner\" programs bundled with the software, users could decline the installation.[\\[51\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-verge-epicscale-51)[\\[52\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-engadget-52)[\\[53\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-torrentfreakriskware-53) On 28 March, Epic Scale was removed from the installation and dropped from the list of software bundle partners.[\\[54\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-54)\n\nBeginning in 2018, advertisements for [Yandex Browser](https:\/\/en.wikipedia.org\/wiki\/Yandex_Browser \"Yandex Browser\") and other Yandex-produced software were included in Russian and Ukrainian versions of μTorrent.[\\[55\\]](https:\/\/en.wikipedia.org\/wiki\/%CE%9CTorrent#cite_note-55)\n\nIn 2005, an [admin](https:\/\/en.wikipedia.org\/wiki\/Internet_forum#Administrators \"Internet forum\") on the μTorrent forums wrote: \"I don't really know how it's pronounced, I usually say 'you torrent' because it looks like a u\".

Initial release September 18, 2005 ; 20 years ago Stable release(s) Windows 3.6.0.47006 [ 1 ] / 11 January 2024 ; 2 years ago macOS 1.8.7.45548 [ 2 ] / 30 January 2020 ; 6 years ago Android 8.2.2 [ 3 ] / 21 March 2024 ; 2 years ago Preview release(s) [±] 3.6.0 Beta (build 46588) (14 November 2022 ; 3 years ago ) [±] [ 4 ] Written in C++ [ 5 ] Operating system Android , [ 6 ] Linux (Server version only, only officially supports very old versions of Debian and Ubuntu ), [ 7 ] Microsoft Windows , [ 8 ] macOS [ 9 ] Available in 60+ languages Type BitTorrent client License Adware Website www .utorrent .com μTorrent , or uTorrent (see pronunciation ), is a proprietary adware BitTorrent client owned and developed by Rainberry, Inc. [ 10 ] The " μ " (Greek letter " mu ") in its name comes from the SI prefix " micro- ", referring to the program's small memory footprint : the program was designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as Vuze or BitComet . μTorrent became controversial in 2015 when many users unknowingly accepted a default option during installation which also installed a cryptocurrency miner . [ 11 ] The program has been in active development since its first release in 2005. Although originally developed by Ludvig Strigeus , since December 7, 2006, the code is owned and maintained by BitTorrent, Inc . [ 12 ] The code has also been employed by BitTorrent, Inc. as the basis for version 6.0 and above of the BitTorrent client , a re-branded version of μTorrent. All versions are written in C++ . [ 5 ] Out of general discontent with bloatware , Serge Paquet suggested to Ludvig Strigeus that he should make a smaller and more efficient BitTorrent client. Strigeus began to conceptualize the plans for the program's development, which, at the time, did not include making the client feature-rich. After initially working on it for about a month during the last quarter of 2004 (the first build is dated October 17, 2004), mostly during his free time before and after work, Strigeus ceased coding μTorrent for a year. He resumed work on September 15, 2005, and three days later, the first public release (version 1.1 beta) was made available as free software , and began generating feedback. On March 4, 2006, PeerFactor SARL announced the signing of a six-month contract with Strigeus for the development of "new content distribution applications on the Web". [ 13 ] PeerFactor SARL was a relatively new company formed by former employees of PeerFactor, which was a subsidiary of the French anti-piracy organization Retspan . Strigeus stated that his coding for PeerFactor SARL was to use his expertise in the optimization of the BitTorrent protocol to create a .dll which PeerFactor SARL intended to use as part of a distribution platform for files in a corporate setting. [ 14 ] At the time there was some speculation that μTorrent may have been modified to spy on users on Peerfactor's behalf, [ 13 ] [ 15 ] however to date (even following μTorrent's acquisition by BitTorrent, Inc.) no evidence has been produced to support these allegations. On December 7, 2006, μTorrent was purchased by BitTorrent, Inc. [ 12 ] It was later announced that BitTorrent paid an undisclosed amount to Spotify for this purchase, the then owner of the software. [ 16 ] On September 18, 2007, BitTorrent 6.0 was released. Although previous versions of the BitTorrent client had been open source software , with version 6 it became proprietary. In April 2017, BitTorrent founder Bram Cohen announced that the next version of μTorrent would be web browser based. This μTorrent version allows users to stream torrents from the default web browser, similar to a regular streaming site . [ 17 ] Features present in μTorrent include: Magnet Links (URIs), added in version 1.8, released on August 9, 2008. [ 18 ] Teredo tunneling / IPv6 support Micro Transport Protocol (μTP) preliminary support as of 1.8.2 with full-support added in 2.0 UPnP support for all versions of Windows, without needing Windows XP 's UPnP framework Protocol encryption (PE) Peer exchange (PEX) with other BitTorrent clients: libtorrent and clients based on it like Deluge or qBittorrent have full μTorrent PEX support Transmission and clients based on libTransmission have full μTorrent PEX support KTorrent has full μTorrent PEX support as of 2.1 RC1 Vuze , formerly Azureus, has full support as of version 3.0.4.3 RSS (" broadcatching ") " Trackerless " BitTorrent support using DHT , compatible with the original BitTorrent client and BitComet User configurable intelligent disk caching system Full proxy server support HTTPS tracker support Configurable bandwidth scheduler Localized for 67 languages. [ 19 ] Initial seeding of torrents Customizable search bar & user interface design. [ 20 ] Configuration settings and temporary files are stored in a single directory, allowing portable use WebUI : A plugin currently in beta testing that allows μTorrent running on one computer to be controlled from another computer, either across the internet or on a LAN , using a Web browser Embedded Tracker : a simple tracker designed for seeding torrents, lacking a web interface or list of hosted torrents. It is not designed for secure or large-scale application. [ 21 ] Quick-resumes interrupted transfers Two "easter eggs" in the About subsection of Help: clicking the μTorrent logo plays a Deep Note -like sound effect, and typing the letter "t" starts a Tetris -like game called μTris, [ 22 ] [ 23 ] [ 24 ] which in 2008 was selected as #1 of the "Top 10 Software Easter Eggs" by LifeHacker . [ 25 ] The ability to use encryption of all traffic to bypass torrent blocking on the network. [ 26 ] μTorrent is shipped as a single stand-alone compressed executable file, installed at first run. Recent versions have included the ability to install themselves on first run. Small executable size is achieved by avoiding the use of many libraries , notably the C++ standard library and stream facilities , and creating substitutes written specifically for the program. The executable is then compressed to roughly half of its compiled and linked size using UPX . Operating system support [ edit ] Screenshot of the macOS version of μTorrent (up to 0.9.2) μTorrent is available for Microsoft Windows , macOS , and Android . [ 6 ] [ 27 ] A μTorrent Server is also available for Linux . [ 28 ] Currently, μTorrent supports Windows XP or later, Mac OS X Snow Leopard or later, and Android 5.0 or later. [ 27 ] The latest version for Windows XP is 3.5.5 build 45311 Stable [ 29 ] [ 30 ] dated July 22, 2019. [ 31 ] However, the official termination of support for Windows XP has not been reported. On the official website of the program, this operating system is still listed as supported. [ 32 ] The first test version for macOS, running on Mac OS X Leopard , was released on 27 November 2008. [ 33 ] On September 2, 2010, the native Linux version of μTorrent Server was released. Firon, an administrator of the μTorrent community forum, said that they had been working on this project for a few months prior to the release as it was the most requested feature for some time. This release is intended for users who are seeking a fast command-line interface based BitTorrent client with a remote web-based management. They also mentioned that a full featured client with a GUI is a work in progress. [ 34 ] As of 2020, μTorrent server for Linux supports Debian 6.0 or later and Ubuntu 12 or later, with both 32-bit & 64-bit options available. [ 35 ] On August 1, 2019, μTorrent announced that users who upgrade to macOS Catalina will be upgraded to μTorrent web automatically since that version of macOS (and subsequent releases) supports 64-bit applications only. [ 36 ] In early versions by Strigeus, μTorrent displayed advertisements in a frame on the web browser by a built-in web redirection via nanotorrent for search queries entered through the search bar. Some users thought this suspicious because IP address tracking could be implemented by recording which machine was downloading/receiving the advertisements, and user-query tracking could easily be done through whichever web interface the client was using. After a short time, that method of advertising was disabled, mitigating those concerns. [ 37 ] A later version of the software displays advertisements (server-side) in a frame at the top of the browser each time the "search all sites" function is used. In version 1.5, no ads are present in the program itself. As of build 463, a redirect bypass feature became available in the Advanced options. As of version 1.8.2, the μTorrent installer downloads and installs the Ask.com toolbar on the first run of the program; the user can opt out of installing that toolbar by deselecting it before allowing the μTorrent installation to proceed. [ 38 ] [ 39 ] The developers stated the addition was needed for funds to continue development. In late 2010, the Ask.com toolbar was replaced with the Conduit Engine . Currently, μTorrent generates revenue through in-content advertisements (in the free version for Windows) and the "pro" version, which is available in 3 bundles (available for both classic & web client for Windows). [ 40 ] In late 2010, some controversy arose with the release of μTorrent which included adware in the form of the Conduit Engine, which installed a toolbar, and made homepage and default search engine changes to a user's web browser. A number of users reported that the installation was made without the user's consent. [ 41 ] There were some complaints that the adware software was difficult to remove. [ 42 ] In 2011, μTorrent bundled the Bing Toolbar . [ 43 ] On July 15, 2011, BitTorrent announced that they would offer a paid version of μTorrent called "μTorrent Plus". This new version would offer extra features, such as integrated file conversion, anti-virus, and a built-in media player. [ 44 ] On 6 October 2011, the Pre-alpha of μTorrent Plus was released to an invitation-only community. [ 45 ] As of December 2011, μTorrentPlus 3.1 was available for $24.95; as of December 2014, the Plus version was available as a $19.95 yearly subscription. In August 2012, BitTorrent announced the addition of advertising in the free version of μTorrent; each ad could only be dismissed after the user had viewed it. [ 46 ] Due to response from users, a few days later, the company stated that ads could be optionally turned off. [ 47 ] A user-created tool known as "Pimp My μTorrent" was also created to simplify the process of disabling ads in the Windows version. [ 48 ] Starting with μTorrent version 3.2.2, the software also contains in-content advertisements described as "Featured Torrent". [ 49 ] As with the other ads, it is possible to disable this content. [ 49 ] In March 2015, μTorrent began automatically installing a background application called Epic Scale to mine cryptocurrency for the benefit of BitTorrent, Inc., while allegedly giving a portion to charity. [ 50 ] Epic Scale mines Litecoin using both CPU and GPU power, and is classified as " riskware " by some security programs. A μTorrent developer disputed whether the automatic installation was really automatic, and claimed that as with all other "partner" programs bundled with the software, users could decline the installation. [ 51 ] [ 52 ] [ 53 ] On 28 March, Epic Scale was removed from the installation and dropped from the list of software bundle partners. [ 54 ] Beginning in 2018, advertisements for Yandex Browser and other Yandex-produced software were included in Russian and Ukrainian versions of μTorrent. [ 55 ] In 2005, an admin on the μTorrent forums wrote: "I don't really know how it's pronounced, I usually say 'you torrent' because it looks like a u". While stating they were not sure, they mentioned that the correct pronunciations for "μTorrent" could be "microtorrent", "mytorrent" (as "my" [myː] is the Swedish pronunciation of the Greek letter μ) and "mutorrent". [ 56 ] In Greece, where the software was widely used, it is called me torrent , [ citation needed ] since the letter μ of the Greek Alphabet is pronounced mi in modern Greek. [ 57 ] The symbol μ is the lowercase Greek letter mu , which stands for the SI prefix " micro- ". It refers to the program's originally small footprint. [ citation needed ] μTorrent was created and initially developed by Ludvig Strigeus ("ludde", from Sweden ). Serge Paquet ("vurlix", from Canada ) acted as release coordinator, and had intended to work on porting the software to Linux and macOS. He maintained the μTorrent website and forum until the end of 2005 but is no longer affiliated with μTorrent. Since its purchase in 2006, development has been performed by various employees of Bittorrent Inc.; Strigeus is no longer affiliated with μTorrent. This section's factual accuracy may be compromised due to out-of-date information . Please help update this article to reflect recent events or newly available information. ( February 2026 ) μTorrent has been praised for its small size and minimal computer resources used, which set it apart from other clients. PC Magazine stated that it "packs an outstanding array of features" in 2006 [ 58 ] and listed it in their 2008 "Best free 157 software tools". [ 59 ] It was also in PC World 's "101 Fantastic freebies". [ 60 ] The website TorrentFreak .com said it was the most feature rich BitTorrent client available, [ 61 ] later summarizing a 2009 University of California, Riverside study [ 62 ] which concluded that "μTorrent Download Speeds Beat Vuze By 16%" on average and "on 10% of [the 30 most used] ISPs, μTorrent users were downloading 30% faster than Vuze users". [ 63 ] About.com said it was the best BitTorrent client available, citing its small size and "minimal impact to the rest of your computer's speed." [ 64 ] Wired.com said its "memory footprint is also ridiculously small". [ 65 ] PC & Tech Authority magazine (Australia) gave it 6 stars (out of 6). [ 66 ] Lifehacker.com rated it the best BitTorrent client available (Windows) in 2008, [ 67 ] 2011 (Windows [ 68 ] and Mac [ 69 ] ) and a follow-up user poll rated it the most popular torrent client in 2015. [ 70 ] CNET .com gave it 5 stars (of 5) saying it features "light and quick downloading". [ 71 ] In November 2009, 52 million users were reported to be using the application, [ 72 ] and in late 2011, 132 million. [ 73 ] According to a study by Arbor Networks , the 2008 adoption of IPv6 by μTorrent caused a 15-fold increase in IPv6 traffic across the Internet over a ten-month period.

"Rainberry, Inc.")[\[10\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-10) The "[μ](https://en.wikipedia.org/wiki/%CE%9C "Μ")" (Greek letter "[mu](https://en.wikipedia.org/wiki/Greek_alphabet "Greek alphabet")") in its name comes from the [SI prefix](https://en.wikipedia.org/wiki/Metric_prefix "Metric prefix") "[micro-](https://en.wikipedia.org/wiki/Micro- "Micro-")", referring to the program's small [memory footprint](https://en.wikipedia.org/wiki/Memory_footprint "Memory footprint"): the program was designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as [Vuze](https://en.wikipedia.org/wiki/Vuze "Vuze") or [BitComet](https://en.wikipedia.org/wiki/BitComet "BitComet"). μTorrent became controversial in 2015 when many users unknowingly accepted a default option during installation which also installed a [cryptocurrency miner](https://en.wikipedia.org/wiki/Cryptocurrency_mining "Cryptocurrency mining").[\[11\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-11) The program has been in active development since its first release in 2005. Although originally developed by [Ludvig Strigeus](https://en.wikipedia.org/wiki/Ludvig_Strigeus "Ludvig Strigeus"), since December 7, 2006, the code is owned and maintained by [BitTorrent, Inc](https://en.wikipedia.org/wiki/Rainberry,_Inc. "Rainberry, Inc.").[\[12\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-purchase-12) The code has also been employed by BitTorrent, Inc. as the basis for version 6.0 and above of the [BitTorrent client](https://en.wikipedia.org/wiki/BitTorrent_$software$ "BitTorrent (software)"), a re-branded version of μTorrent. All versions are written in [C++](https://en.wikipedia.org/wiki/C%2B%2B "C++").[\[5\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-C++-5) ## History \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=1 "Edit section: History")\] ### Early development \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=2 "Edit section: Early development")\] Out of general discontent with [bloatware](https://en.wikipedia.org/wiki/Bloatware "Bloatware"), Serge Paquet suggested to [Ludvig Strigeus](https://en.wikipedia.org/wiki/Ludvig_Strigeus "Ludvig Strigeus") that he should make a smaller and more efficient BitTorrent client. Strigeus began to conceptualize the plans for the program's development, which, at the time, did not include making the client feature-rich. After initially working on it for about a month during the last quarter of 2004 (the first build is dated October 17, 2004), mostly during his free time before and after work, Strigeus ceased coding μTorrent for a year. He resumed work on September 15, 2005, and three days later, the first public release (version 1.1 beta) was made available as [free software](https://en.wikipedia.org/wiki/Free_software "Free software"), and began generating feedback. ### PeerFactor SARL \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=3 "Edit section: PeerFactor SARL")\] On March 4, 2006, PeerFactor SARL announced the signing of a six-month contract with Strigeus for the development of "new content distribution applications on the Web".[\[13\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-slickpeerfactorSARL-13) PeerFactor SARL was a relatively new company formed by former employees of PeerFactor, which was a subsidiary of the French anti-piracy organization [Retspan](https://en.wikipedia.org/wiki/Retspan "Retspan"). Strigeus stated that his coding for PeerFactor SARL was to use his expertise in the optimization of the BitTorrent [protocol](https://en.wikipedia.org/wiki/Protocol_$computing$ "Protocol (computing)") to create a [.dll](https://en.wikipedia.org/wiki/Dynamic-link_library "Dynamic-link library") which PeerFactor SARL intended to use as part of a distribution platform for files in a corporate setting.[\[14\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-14) At the time there was some speculation that μTorrent may have been modified to spy on users on Peerfactor's behalf,[\[13\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-slickpeerfactorSARL-13)[\[15\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-15) however to date (even following μTorrent's acquisition by BitTorrent, Inc.) no evidence has been produced to support these allegations. ### Ownership change \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=4 "Edit section: Ownership change")\] On December 7, 2006, μTorrent was purchased by [BitTorrent, Inc.](https://en.wikipedia.org/wiki/BitTorrent_$company$ "BitTorrent (company)")[\[12\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-purchase-12) It was later announced that BitTorrent paid an undisclosed amount to [Spotify](https://en.wikipedia.org/wiki/Spotify "Spotify") for this purchase, the then owner of the software.[\[16\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-16) On September 18, 2007, [BitTorrent](https://en.wikipedia.org/wiki/BitTorrent_$software$ "BitTorrent (software)") 6.0 was released. Although previous versions of the BitTorrent client had been [open source software](https://en.wikipedia.org/wiki/Open_source_software "Open source software"), with version 6 it became proprietary. In April 2017, BitTorrent founder [Bram Cohen](https://en.wikipedia.org/wiki/Bram_Cohen "Bram Cohen") announced that the next version of μTorrent would be [web browser](https://en.wikipedia.org/wiki/Web_browser "Web browser") based. This μTorrent version allows users to stream torrents from the default web browser, similar to a regular [streaming site](https://en.wikipedia.org/wiki/Streaming_media "Streaming media").[\[17\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-17) ## Features \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=5 "Edit section: Features")\] Features present in μTorrent include: - [Magnet Links](https://en.wikipedia.org/wiki/Magnet_URI_scheme "Magnet URI scheme") (URIs), added in version 1.8, released on August 9, 2008.[\[18\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-%CE%BCTorrent_1.8_Changelog_noting_Magnet_Link_support-18) - [Teredo tunneling](https://en.wikipedia.org/wiki/Teredo_tunneling "Teredo tunneling") / [IPv6](https://en.wikipedia.org/wiki/IPv6 "IPv6") support - [Micro Transport Protocol](https://en.wikipedia.org/wiki/Micro_Transport_Protocol "Micro Transport Protocol") (μTP) preliminary support as of 1.8.2 with full-support added in 2.0 - [UPnP](https://en.wikipedia.org/wiki/Universal_Plug_and_Play "Universal Plug and Play") support for all versions of Windows, without needing [Windows XP](https://en.wikipedia.org/wiki/Windows_XP "Windows XP")'s UPnP [framework](https://en.wikipedia.org/wiki/Software_framework "Software framework") - [Protocol encryption](https://en.wikipedia.org/wiki/BitTorrent_protocol_encryption "BitTorrent protocol encryption") (PE) - [Peer exchange](https://en.wikipedia.org/wiki/Peer_exchange "Peer exchange") (PEX) with other BitTorrent clients: - [libtorrent](https://en.wikipedia.org/wiki/Libtorrent "Libtorrent") and clients based on it like [Deluge](https://en.wikipedia.org/wiki/Deluge_$BitTorrent_client$ "Deluge (BitTorrent client)") or [qBittorrent](https://en.wikipedia.org/wiki/QBittorrent "QBittorrent") have full μTorrent PEX support - [Transmission](https://en.wikipedia.org/wiki/Transmission_$BitTorrent_client$ "Transmission (BitTorrent client)") and clients based on libTransmission have full μTorrent PEX support - [KTorrent](https://en.wikipedia.org/wiki/KTorrent "KTorrent") has full μTorrent PEX support as of 2.1 RC1 - [Vuze](https://en.wikipedia.org/wiki/Vuze "Vuze"), formerly Azureus, has full support as of version 3.0.4.3 - [RSS](https://en.wikipedia.org/wiki/RSS "RSS") ("[broadcatching](https://en.wikipedia.org/wiki/Broadcatching "Broadcatching")") - "[Trackerless](https://en.wikipedia.org/wiki/BitTorrent_tracker#Trackerless_torrents "BitTorrent tracker")" BitTorrent support using [DHT](https://en.wikipedia.org/wiki/Distributed_hash_table "Distributed hash table"), compatible with the original [BitTorrent client](https://en.wikipedia.org/wiki/BitTorrent_client "BitTorrent client") and [BitComet](https://en.wikipedia.org/wiki/BitComet "BitComet") - User configurable intelligent disk [caching](https://en.wikipedia.org/wiki/Cache_$computing$ "Cache (computing)") system - [Full proxy server](https://en.wikipedia.org/wiki/Proxy_server "Proxy server") support - [HTTPS](https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol_over_Secure_Socket_Layer "Hypertext Transfer Protocol over Secure Socket Layer") tracker support - Configurable [bandwidth](https://en.wikipedia.org/wiki/Bandwidth_$computing$ "Bandwidth (computing)") scheduler - [Localized](https://en.wikipedia.org/wiki/Software_localization "Software localization") for 67 languages.[\[19\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-19) - [Initial seeding](https://en.wikipedia.org/wiki/Super-seeding "Super-seeding") of torrents - Customizable [search bar](https://en.wikipedia.org/wiki/Search_bar "Search bar") & user interface design.[\[20\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-20) - Configuration settings and temporary files are stored in a single directory, allowing portable use - [WebUI](https://en.wikipedia.org/wiki/User_interface#Types "User interface"): A [plugin](https://en.wikipedia.org/wiki/Plug-in_$computing$ "Plug-in (computing)") currently in [beta testing](https://en.wikipedia.org/wiki/Beta_testing "Beta testing") that allows μTorrent running on one computer to be controlled from another computer, either across the internet or on a [LAN](https://en.wikipedia.org/wiki/LAN "LAN"), using a [Web browser](https://en.wikipedia.org/wiki/Web_browser "Web browser") - [Embedded Tracker](https://en.wikipedia.org/wiki/BitTorrent_tracker "BitTorrent tracker"): a simple tracker designed for seeding torrents, lacking a web interface or list of hosted torrents.

Recent versions have included the ability to install themselves on first run. Small executable size is achieved by avoiding the use of many [libraries](https://en.wikipedia.org/wiki/Library_$computer_science$ "Library (computer science)"), notably the [C++ standard library](https://en.wikipedia.org/wiki/C%2B%2B_Standard_Library "C++ Standard Library") and [stream facilities](https://en.wikipedia.org/wiki/Iostream "Iostream"), and creating substitutes written specifically for the program. The executable is then compressed to roughly half of its compiled and linked size using [UPX](https://en.wikipedia.org/wiki/UPX "UPX"). ### Operating system support \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=7 "Edit section: Operating system support")\] [![](https://upload.wikimedia.org/wikipedia/en/thumb/8/85/%CE%9CTorrentMac.png/250px-%CE%9CTorrentMac.png)](https://en.wikipedia.org/wiki/File:%CE%9CTorrentMac.png) Screenshot of the macOS version of μTorrent (up to 0.9.2) μTorrent is available for [Microsoft Windows](https://en.wikipedia.org/wiki/Microsoft_Windows "Microsoft Windows"), [macOS](https://en.wikipedia.org/wiki/MacOS "MacOS"), and [Android](https://en.wikipedia.org/wiki/Android_$operating_system$ "Android (operating system)").[\[6\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-google_play-6)[\[27\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-Reqs-27) A μTorrent Server is also available for [Linux](https://en.wikipedia.org/wiki/Linux "Linux").[\[28\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-Linux-28) Currently, μTorrent supports [Windows XP](https://en.wikipedia.org/wiki/Windows_XP "Windows XP") or later, [Mac OS X Snow Leopard](https://en.wikipedia.org/wiki/Mac_OS_X_Snow_Leopard "Mac OS X Snow Leopard") or later, and [Android 5.0](https://en.wikipedia.org/wiki/Android_Lollipop "Android Lollipop") or later.[\[27\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-Reqs-27) The latest version for Windows XP is 3.5.5 build 45311 Stable[\[29\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-29)[\[30\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-30) dated July 22, 2019.[\[31\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-31) However, the official termination of support for Windows XP has not been reported. On the official website of the program, this operating system is still listed as supported.[\[32\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-32) The first test version for macOS, running on [Mac OS X Leopard](https://en.wikipedia.org/wiki/Mac_OS_X_Leopard "Mac OS X Leopard"), was released on 27 November 2008.[\[33\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-33) On September 2, 2010, the native [Linux](https://en.wikipedia.org/wiki/Linux "Linux") version of μTorrent Server was released. Firon, an administrator of the μTorrent community forum, said that they had been working on this project for a few months prior to the release as it was the most requested feature for some time. This release is intended for users who are seeking a fast [command-line interface](https://en.wikipedia.org/wiki/Command-line_interface "Command-line interface") based [BitTorrent](https://en.wikipedia.org/wiki/BitTorrent_$protocol$ "BitTorrent (protocol)") client with a remote web-based management. They also mentioned that a full featured client with a [GUI](https://en.wikipedia.org/wiki/GUI "GUI") is a work in progress.[\[34\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-utorrent1-34) As of 2020, μTorrent server for Linux supports [Debian](https://en.wikipedia.org/wiki/Debian "Debian") 6.0 or later and [Ubuntu](https://en.wikipedia.org/wiki/Ubuntu "Ubuntu") 12 or later, with both 32-bit & 64-bit options available.[\[35\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-35) On August 1, 2019, μTorrent announced that users who upgrade to [macOS Catalina](https://en.wikipedia.org/wiki/MacOS_Catalina "MacOS Catalina") will be upgraded to μTorrent web automatically since that version of macOS (and subsequent releases) supports 64-bit applications only.[\[36\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-36) ## Revenue \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=8 "Edit section: Revenue")\] In early versions by Strigeus, μTorrent displayed advertisements in a frame on the web browser by a built-in web redirection via nanotorrent for search queries entered through the search bar. Some users thought this suspicious because [IP address](https://en.wikipedia.org/wiki/IP_address "IP address") tracking could be implemented by recording which machine was downloading/receiving the advertisements, and user-query tracking could easily be done through whichever web interface the client was using. After a short time, that method of advertising was disabled, mitigating those concerns.[\[37\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-37) A later version of the software displays advertisements (server-side) in a frame at the top of the browser each time the "search all sites" function is used. In version 1.5, no ads are present in the program itself. As of build 463, a redirect bypass feature became available in the Advanced options. As of version 1.8.2, the μTorrent installer downloads and installs the [Ask.com toolbar](https://en.wikipedia.org/wiki/Ask.com_toolbar "Ask.com toolbar") on the first run of the program; the user can opt out of installing that toolbar by deselecting it before allowing the μTorrent installation to proceed.[\[38\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-38)[\[39\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-39) The developers stated the addition was needed for funds to continue development. In late 2010, the Ask.com toolbar was replaced with the [Conduit Engine](https://en.wikipedia.org/wiki/Conduit_$publisher_network_and_platform$ "Conduit (publisher network and platform)"). Currently, μTorrent generates revenue through in-content advertisements (in the free version for Windows) and the "pro" version, which is available in 3 bundles (available for both classic & web client for Windows).[\[40\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-40) ### Toolbars \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=9 "Edit section: Toolbars")\] In late 2010, some controversy arose with the release of μTorrent which included [adware](https://en.wikipedia.org/wiki/Adware "Adware") in the form of the [Conduit](https://en.wikipedia.org/wiki/Conduit_$publisher_network_and_platform$ "Conduit (publisher network and platform)") Engine, which installed a toolbar, and made homepage and default search engine changes to a user's web browser. A number of users reported that the installation was made without the user's consent.[\[41\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-41) There were some complaints that the adware software was difficult to remove.[\[42\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-42) In 2011, μTorrent bundled the [Bing Toolbar](https://en.wikipedia.org/wiki/Bing_Toolbar "Bing Toolbar").[\[43\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-43) ### Paid version \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=10 "Edit section: Paid version")\] On July 15, 2011, BitTorrent announced that they would offer a paid version of μTorrent called "μTorrent Plus". This new version would offer extra features, such as integrated file conversion, anti-virus, and a built-in media player.[\[44\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-%CE%BCTorrent_plus_announcement-44) On 6 October 2011, the [Pre-alpha](https://en.wikipedia.org/wiki/Pre-alpha "Pre-alpha") of μTorrent Plus was released to an invitation-only community.[\[45\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-%CE%BCTorrent_plus_update-45) As of December 2011, μTorrentPlus 3.1 was available for \$24.95; as of December 2014, the Plus version was available as a \$19.95 yearly subscription. ### Ads and malware \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=11 "Edit section: Ads and malware")\] In August 2012, BitTorrent announced the addition of [advertising](https://en.wikipedia.org/wiki/Advertising "Advertising") in the free version of μTorrent; each ad could only be dismissed after the user had viewed it.[\[46\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-46) Due to response from users, a few days later, the company stated that ads could be optionally turned off.[\[47\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-47) A user-created tool known as "Pimp My μTorrent" was also created to simplify the process of disabling ads in the Windows version.[\[48\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-48) Starting with μTorrent version 3.2.2, the software also contains in-content advertisements described as "Featured Torrent".[\[49\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-in-content-ads-49) As with the other ads, it is possible to disable this content.[\[49\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-in-content-ads-49) In March 2015, μTorrent began automatically installing a background application called Epic Scale to mine [cryptocurrency](https://en.wikipedia.org/wiki/Cryptocurrency "Cryptocurrency") for the benefit of BitTorrent, Inc., while allegedly giving a portion to charity.[\[50\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-50) Epic Scale mines [Litecoin](https://en.wikipedia.org/wiki/Litecoin "Litecoin") using both [CPU](https://en.wikipedia.org/wiki/CPU "CPU") and [GPU](https://en.wikipedia.org/wiki/GPU "GPU") power, and is classified as "[riskware](https://en.wikipedia.org/wiki/Riskware "Riskware")" by some security programs. A μTorrent developer disputed whether the automatic installation was really automatic, and claimed that as with all other "partner" programs bundled with the software, users could decline the installation.[\[51\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-verge-epicscale-51)[\[52\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-engadget-52)[\[53\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-torrentfreakriskware-53) On 28 March, Epic Scale was removed from the installation and dropped from the list of software bundle partners.[\[54\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-54) Beginning in 2018, advertisements for [Yandex Browser](https://en.wikipedia.org/wiki/Yandex_Browser "Yandex Browser") and other Yandex-produced software were included in Russian and Ukrainian versions of μTorrent.[\[55\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-55) ## Pronunciation \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=12 "Edit section: Pronunciation")\] In 2005, an [admin](https://en.wikipedia.org/wiki/Internet_forum#Administrators "Internet forum") on the μTorrent forums wrote: "I don't really know how it's pronounced, I usually say 'you torrent' because it looks like a u". While stating they were not sure, they mentioned that the correct pronunciations for "μTorrent" could be "microtorrent", "mytorrent" (as "my" [\[myː\]](https://en.wikipedia.org/wiki/Help:IPA/Swedish "Help:IPA/Swedish") is the Swedish pronunciation of the Greek letter μ) and "mutorrent".[\[56\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-56) In Greece, where the software was widely used, it is called me torrent,\[[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed "Wikipedia:Citation needed")\] since the letter μ of the Greek Alphabet is pronounced mi in modern Greek.[\[57\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-Greek_Alphabet_&_Writing:_An_Introduction-57) The symbol μ is the lowercase [Greek](https://en.wikipedia.org/wiki/Greek_language "Greek language") letter [mu](https://en.wikipedia.org/wiki/Mu_$letter$ "Mu (letter)"), which stands for the [SI prefix](https://en.wikipedia.org/wiki/SI_prefix "SI prefix") "[micro-](https://en.wikipedia.org/wiki/Micro- "Micro-")". It refers to the program's originally small footprint.\[[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed "Wikipedia:Citation needed")\] ## Contributors \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=13 "Edit section: Contributors")\] μTorrent was created and initially developed by [Ludvig Strigeus](https://en.wikipedia.org/wiki/Ludvig_Strigeus "Ludvig Strigeus") ("ludde", from [Sweden](https://en.wikipedia.org/wiki/Sweden "Sweden")). Serge Paquet ("vurlix", from [Canada](https://en.wikipedia.org/wiki/Canada "Canada")) acted as release coordinator, and had intended to work on porting the software to Linux and macOS. He maintained the μTorrent website and forum until the end of 2005 but is no longer affiliated with μTorrent. Since its purchase in 2006, development has been performed by various employees of Bittorrent Inc.; Strigeus is no longer affiliated with μTorrent. ## Reception \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=14 "Edit section: Reception")\] \| \| \| \|---\|---\| \| ![](https://upload.wikimedia.org/wikipedia/commons/thumb/5/53/Ambox_current_red_Americas.svg/60px-Ambox_current_red_Americas.svg.png) \| This section's [factual accuracy](https://en.wikipedia.org/wiki/Wikipedia:Accuracy_dispute "Wikipedia:Accuracy dispute") may be compromised due to out-of-date information.

[PC Magazine](https://en.wikipedia.org/wiki/PC_Magazine "PC Magazine") stated that it "packs an outstanding array of features" in 2006[\[58\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-58) and listed it in their 2008 "Best free 157 software tools".[\[59\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-59) It was also in [PC World](https://en.wikipedia.org/wiki/PC_World_$magazine$ "PC World (magazine)")'s "101 Fantastic freebies".[\[60\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-60) The website [TorrentFreak](https://en.wikipedia.org/wiki/TorrentFreak "TorrentFreak").com said it was the most feature rich BitTorrent client available,[\[61\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-61) later summarizing a 2009 [University of California, Riverside](https://en.wikipedia.org/wiki/University_of_California,_Riverside "University of California, Riverside") study[\[62\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-62) which concluded that "μTorrent Download Speeds Beat Vuze By 16%" on average and "on 10% of \[the 30 most used\] ISPs, μTorrent users were downloading 30% faster than Vuze users".[\[63\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-63) [About.com](https://en.wikipedia.org/wiki/About.com "About.com") said it was the best BitTorrent client available, citing its small size and "minimal impact to the rest of your computer's speed."[\[64\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-64) [Wired.com](https://en.wikipedia.org/wiki/Wired.com "Wired.com") said its "memory footprint is also ridiculously small".[\[65\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-65) PC & Tech Authority magazine (Australia) gave it 6 stars (out of 6).[\[66\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-66) [Lifehacker.com](https://en.wikipedia.org/wiki/Lifehacker.com "Lifehacker.com") rated it the best BitTorrent client available (Windows) in 2008,[\[67\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-67) 2011 (Windows[\[68\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-68) and Mac[\[69\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-69)) and a follow-up user poll rated it the most popular torrent client in 2015.[\[70\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-lifehacker2015-70) [CNET](https://en.wikipedia.org/wiki/CNET "CNET").com gave it 5 stars (of 5) saying it features "light and quick downloading".[\[71\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-71) In November 2009, 52 million users were reported to be using the application,[\[72\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-72) and in late 2011, 132 million.[\[73\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-73) According to a study by [Arbor Networks](https://en.wikipedia.org/wiki/Arbor_Networks "Arbor Networks"), the 2008 adoption of [IPv6](https://en.wikipedia.org/wiki/IPv6 "IPv6") by μTorrent caused a 15-fold increase in IPv6 traffic across the Internet over a ten-month period.[\[74\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-74) ## See also \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=15 "Edit section: See also")\] - [Comparison of BitTorrent clients](https://en.wikipedia.org/wiki/Comparison_of_BitTorrent_clients "Comparison of BitTorrent clients") ## References \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=16 "Edit section: References")\] 1.

"Rainberry, Inc.")[\[10\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-10) The "[μ](https://en.wikipedia.org/wiki/%CE%9C "Μ")" (Greek letter "[mu](https://en.wikipedia.org/wiki/Greek_alphabet "Greek alphabet")") in its name comes from the [SI prefix](https://en.wikipedia.org/wiki/Metric_prefix "Metric prefix") "[micro-](https://en.wikipedia.org/wiki/Micro- "Micro-")", referring to the program's small [memory footprint](https://en.wikipedia.org/wiki/Memory_footprint "Memory footprint"): the program was designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as [Vuze](https://en.wikipedia.org/wiki/Vuze "Vuze") or [BitComet](https://en.wikipedia.org/wiki/BitComet "BitComet"). μTorrent became controversial in 2015 when many users unknowingly accepted a default option during installation which also installed a [cryptocurrency miner](https://en.wikipedia.org/wiki/Cryptocurrency_mining "Cryptocurrency mining").[\[11\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-11) The program has been in active development since its first release in 2005. Although originally developed by [Ludvig Strigeus](https://en.wikipedia.org/wiki/Ludvig_Strigeus "Ludvig Strigeus"), since December 7, 2006, the code is owned and maintained by [BitTorrent, Inc](https://en.wikipedia.org/wiki/Rainberry,_Inc. "Rainberry, Inc.").[\[12\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-purchase-12) The code has also been employed by BitTorrent, Inc. as the basis for version 6.0 and above of the [BitTorrent client](https://en.wikipedia.org/wiki/BitTorrent_$software$ "BitTorrent (software)"), a re-branded version of μTorrent. All versions are written in [C++](https://en.wikipedia.org/wiki/C%2B%2B "C++").[\[5\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-C++-5) Out of general discontent with [bloatware](https://en.wikipedia.org/wiki/Bloatware "Bloatware"), Serge Paquet suggested to [Ludvig Strigeus](https://en.wikipedia.org/wiki/Ludvig_Strigeus "Ludvig Strigeus") that he should make a smaller and more efficient BitTorrent client. Strigeus began to conceptualize the plans for the program's development, which, at the time, did not include making the client feature-rich. After initially working on it for about a month during the last quarter of 2004 (the first build is dated October 17, 2004), mostly during his free time before and after work, Strigeus ceased coding μTorrent for a year. He resumed work on September 15, 2005, and three days later, the first public release (version 1.1 beta) was made available as [free software](https://en.wikipedia.org/wiki/Free_software "Free software"), and began generating feedback. On March 4, 2006, PeerFactor SARL announced the signing of a six-month contract with Strigeus for the development of "new content distribution applications on the Web".[\[13\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-slickpeerfactorSARL-13) PeerFactor SARL was a relatively new company formed by former employees of PeerFactor, which was a subsidiary of the French anti-piracy organization [Retspan](https://en.wikipedia.org/wiki/Retspan "Retspan"). Strigeus stated that his coding for PeerFactor SARL was to use his expertise in the optimization of the BitTorrent [protocol](https://en.wikipedia.org/wiki/Protocol_$computing$ "Protocol (computing)") to create a [.dll](https://en.wikipedia.org/wiki/Dynamic-link_library "Dynamic-link library") which PeerFactor SARL intended to use as part of a distribution platform for files in a corporate setting.[\[14\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-14) At the time there was some speculation that μTorrent may have been modified to spy on users on Peerfactor's behalf,[\[13\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-slickpeerfactorSARL-13)[\[15\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-15) however to date (even following μTorrent's acquisition by BitTorrent, Inc.) no evidence has been produced to support these allegations. On December 7, 2006, μTorrent was purchased by [BitTorrent, Inc.](https://en.wikipedia.org/wiki/BitTorrent_$company$ "BitTorrent (company)")[\[12\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-purchase-12) It was later announced that BitTorrent paid an undisclosed amount to [Spotify](https://en.wikipedia.org/wiki/Spotify "Spotify") for this purchase, the then owner of the software.[\[16\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-16) On September 18, 2007, [BitTorrent](https://en.wikipedia.org/wiki/BitTorrent_$software$ "BitTorrent (software)") 6.0 was released. Although previous versions of the BitTorrent client had been [open source software](https://en.wikipedia.org/wiki/Open_source_software "Open source software"), with version 6 it became proprietary. In April 2017, BitTorrent founder [Bram Cohen](https://en.wikipedia.org/wiki/Bram_Cohen "Bram Cohen") announced that the next version of μTorrent would be [web browser](https://en.wikipedia.org/wiki/Web_browser "Web browser") based. This μTorrent version allows users to stream torrents from the default web browser, similar to a regular [streaming site](https://en.wikipedia.org/wiki/Streaming_media "Streaming media").[\[17\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-17) Features present in μTorrent include: - [Magnet Links](https://en.wikipedia.org/wiki/Magnet_URI_scheme "Magnet URI scheme") (URIs), added in version 1.8, released on August 9, 2008.[\[18\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-%CE%BCTorrent_1.8_Changelog_noting_Magnet_Link_support-18) - [Teredo tunneling](https://en.wikipedia.org/wiki/Teredo_tunneling "Teredo tunneling") / [IPv6](https://en.wikipedia.org/wiki/IPv6 "IPv6") support - [Micro Transport Protocol](https://en.wikipedia.org/wiki/Micro_Transport_Protocol "Micro Transport Protocol") (μTP) preliminary support as of 1.8.2 with full-support added in 2.0 - [UPnP](https://en.wikipedia.org/wiki/Universal_Plug_and_Play "Universal Plug and Play") support for all versions of Windows, without needing [Windows XP](https://en.wikipedia.org/wiki/Windows_XP "Windows XP")'s UPnP [framework](https://en.wikipedia.org/wiki/Software_framework "Software framework") - [Protocol encryption](https://en.wikipedia.org/wiki/BitTorrent_protocol_encryption "BitTorrent protocol encryption") (PE) - [Peer exchange](https://en.wikipedia.org/wiki/Peer_exchange "Peer exchange") (PEX) with other BitTorrent clients: - [libtorrent](https://en.wikipedia.org/wiki/Libtorrent "Libtorrent") and clients based on it like [Deluge](https://en.wikipedia.org/wiki/Deluge_$BitTorrent_client$ "Deluge (BitTorrent client)") or [qBittorrent](https://en.wikipedia.org/wiki/QBittorrent "QBittorrent") have full μTorrent PEX support - [Transmission](https://en.wikipedia.org/wiki/Transmission_$BitTorrent_client$ "Transmission (BitTorrent client)") and clients based on libTransmission have full μTorrent PEX support - [KTorrent](https://en.wikipedia.org/wiki/KTorrent "KTorrent") has full μTorrent PEX support as of 2.1 RC1 - [Vuze](https://en.wikipedia.org/wiki/Vuze "Vuze"), formerly Azureus, has full support as of version 3.0.4.3 - [RSS](https://en.wikipedia.org/wiki/RSS "RSS") ("[broadcatching](https://en.wikipedia.org/wiki/Broadcatching "Broadcatching")") - "[Trackerless](https://en.wikipedia.org/wiki/BitTorrent_tracker#Trackerless_torrents "BitTorrent tracker")" BitTorrent support using [DHT](https://en.wikipedia.org/wiki/Distributed_hash_table "Distributed hash table"), compatible with the original [BitTorrent client](https://en.wikipedia.org/wiki/BitTorrent_client "BitTorrent client") and [BitComet](https://en.wikipedia.org/wiki/BitComet "BitComet") - User configurable intelligent disk [caching](https://en.wikipedia.org/wiki/Cache_$computing$ "Cache (computing)") system - [Full proxy server](https://en.wikipedia.org/wiki/Proxy_server "Proxy server") support - [HTTPS](https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol_over_Secure_Socket_Layer "Hypertext Transfer Protocol over Secure Socket Layer") tracker support - Configurable [bandwidth](https://en.wikipedia.org/wiki/Bandwidth_$computing$ "Bandwidth (computing)") scheduler - [Localized](https://en.wikipedia.org/wiki/Software_localization "Software localization") for 67 languages.[\[19\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-19) - [Initial seeding](https://en.wikipedia.org/wiki/Super-seeding "Super-seeding") of torrents - Customizable [search bar](https://en.wikipedia.org/wiki/Search_bar "Search bar") & user interface design.[\[20\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-20) - Configuration settings and temporary files are stored in a single directory, allowing portable use - [WebUI](https://en.wikipedia.org/wiki/User_interface#Types "User interface"): A [plugin](https://en.wikipedia.org/wiki/Plug-in_$computing$ "Plug-in (computing)") currently in [beta testing](https://en.wikipedia.org/wiki/Beta_testing "Beta testing") that allows μTorrent running on one computer to be controlled from another computer, either across the internet or on a [LAN](https://en.wikipedia.org/wiki/LAN "LAN"), using a [Web browser](https://en.wikipedia.org/wiki/Web_browser "Web browser") - [Embedded Tracker](https://en.wikipedia.org/wiki/BitTorrent_tracker "BitTorrent tracker"): a simple tracker designed for seeding torrents, lacking a web interface or list of hosted torrents.

Recent versions have included the ability to install themselves on first run. Small executable size is achieved by avoiding the use of many [libraries](https://en.wikipedia.org/wiki/Library_$computer_science$ "Library (computer science)"), notably the [C++ standard library](https://en.wikipedia.org/wiki/C%2B%2B_Standard_Library "C++ Standard Library") and [stream facilities](https://en.wikipedia.org/wiki/Iostream "Iostream"), and creating substitutes written specifically for the program. The executable is then compressed to roughly half of its compiled and linked size using [UPX](https://en.wikipedia.org/wiki/UPX "UPX"). ### Operating system support \[[edit](https://en.wikipedia.org/w/index.php?title=%CE%9CTorrent&action=edit&section=7 "Edit section: Operating system support")\] [![](https://upload.wikimedia.org/wikipedia/en/thumb/8/85/%CE%9CTorrentMac.png/250px-%CE%9CTorrentMac.png)](https://en.wikipedia.org/wiki/File:%CE%9CTorrentMac.png) Screenshot of the macOS version of μTorrent (up to 0.9.2) μTorrent is available for [Microsoft Windows](https://en.wikipedia.org/wiki/Microsoft_Windows "Microsoft Windows"), [macOS](https://en.wikipedia.org/wiki/MacOS "MacOS"), and [Android](https://en.wikipedia.org/wiki/Android_$operating_system$ "Android (operating system)").[\[6\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-google_play-6)[\[27\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-Reqs-27) A μTorrent Server is also available for [Linux](https://en.wikipedia.org/wiki/Linux "Linux").[\[28\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-Linux-28) Currently, μTorrent supports [Windows XP](https://en.wikipedia.org/wiki/Windows_XP "Windows XP") or later, [Mac OS X Snow Leopard](https://en.wikipedia.org/wiki/Mac_OS_X_Snow_Leopard "Mac OS X Snow Leopard") or later, and [Android 5.0](https://en.wikipedia.org/wiki/Android_Lollipop "Android Lollipop") or later.[\[27\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-Reqs-27) The latest version for Windows XP is 3.5.5 build 45311 Stable[\[29\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-29)[\[30\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-30) dated July 22, 2019.[\[31\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-31) However, the official termination of support for Windows XP has not been reported. On the official website of the program, this operating system is still listed as supported.[\[32\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-32) The first test version for macOS, running on [Mac OS X Leopard](https://en.wikipedia.org/wiki/Mac_OS_X_Leopard "Mac OS X Leopard"), was released on 27 November 2008.[\[33\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-33) On September 2, 2010, the native [Linux](https://en.wikipedia.org/wiki/Linux "Linux") version of μTorrent Server was released. Firon, an administrator of the μTorrent community forum, said that they had been working on this project for a few months prior to the release as it was the most requested feature for some time. This release is intended for users who are seeking a fast [command-line interface](https://en.wikipedia.org/wiki/Command-line_interface "Command-line interface") based [BitTorrent](https://en.wikipedia.org/wiki/BitTorrent_$protocol$ "BitTorrent (protocol)") client with a remote web-based management. They also mentioned that a full featured client with a [GUI](https://en.wikipedia.org/wiki/GUI "GUI") is a work in progress.[\[34\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-utorrent1-34) As of 2020, μTorrent server for Linux supports [Debian](https://en.wikipedia.org/wiki/Debian "Debian") 6.0 or later and [Ubuntu](https://en.wikipedia.org/wiki/Ubuntu "Ubuntu") 12 or later, with both 32-bit & 64-bit options available.[\[35\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-35) On August 1, 2019, μTorrent announced that users who upgrade to [macOS Catalina](https://en.wikipedia.org/wiki/MacOS_Catalina "MacOS Catalina") will be upgraded to μTorrent web automatically since that version of macOS (and subsequent releases) supports 64-bit applications only.[\[36\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-36) In early versions by Strigeus, μTorrent displayed advertisements in a frame on the web browser by a built-in web redirection via nanotorrent for search queries entered through the search bar. Some users thought this suspicious because [IP address](https://en.wikipedia.org/wiki/IP_address "IP address") tracking could be implemented by recording which machine was downloading/receiving the advertisements, and user-query tracking could easily be done through whichever web interface the client was using. After a short time, that method of advertising was disabled, mitigating those concerns.[\[37\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-37) A later version of the software displays advertisements (server-side) in a frame at the top of the browser each time the "search all sites" function is used. In version 1.5, no ads are present in the program itself. As of build 463, a redirect bypass feature became available in the Advanced options. As of version 1.8.2, the μTorrent installer downloads and installs the [Ask.com toolbar](https://en.wikipedia.org/wiki/Ask.com_toolbar "Ask.com toolbar") on the first run of the program; the user can opt out of installing that toolbar by deselecting it before allowing the μTorrent installation to proceed.[\[38\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-38)[\[39\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-39) The developers stated the addition was needed for funds to continue development. In late 2010, the Ask.com toolbar was replaced with the [Conduit Engine](https://en.wikipedia.org/wiki/Conduit_$publisher_network_and_platform$ "Conduit (publisher network and platform)"). Currently, μTorrent generates revenue through in-content advertisements (in the free version for Windows) and the "pro" version, which is available in 3 bundles (available for both classic & web client for Windows).[\[40\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-40) In late 2010, some controversy arose with the release of μTorrent which included [adware](https://en.wikipedia.org/wiki/Adware "Adware") in the form of the [Conduit](https://en.wikipedia.org/wiki/Conduit_$publisher_network_and_platform$ "Conduit (publisher network and platform)") Engine, which installed a toolbar, and made homepage and default search engine changes to a user's web browser. A number of users reported that the installation was made without the user's consent.[\[41\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-41) There were some complaints that the adware software was difficult to remove.[\[42\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-42) In 2011, μTorrent bundled the [Bing Toolbar](https://en.wikipedia.org/wiki/Bing_Toolbar "Bing Toolbar").[\[43\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-43) On July 15, 2011, BitTorrent announced that they would offer a paid version of μTorrent called "μTorrent Plus". This new version would offer extra features, such as integrated file conversion, anti-virus, and a built-in media player.[\[44\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-%CE%BCTorrent_plus_announcement-44) On 6 October 2011, the [Pre-alpha](https://en.wikipedia.org/wiki/Pre-alpha "Pre-alpha") of μTorrent Plus was released to an invitation-only community.[\[45\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-%CE%BCTorrent_plus_update-45) As of December 2011, μTorrentPlus 3.1 was available for \$24.95; as of December 2014, the Plus version was available as a \$19.95 yearly subscription. In August 2012, BitTorrent announced the addition of [advertising](https://en.wikipedia.org/wiki/Advertising "Advertising") in the free version of μTorrent; each ad could only be dismissed after the user had viewed it.[\[46\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-46) Due to response from users, a few days later, the company stated that ads could be optionally turned off.[\[47\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-47) A user-created tool known as "Pimp My μTorrent" was also created to simplify the process of disabling ads in the Windows version.[\[48\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-48) Starting with μTorrent version 3.2.2, the software also contains in-content advertisements described as "Featured Torrent".[\[49\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-in-content-ads-49) As with the other ads, it is possible to disable this content.[\[49\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-in-content-ads-49) In March 2015, μTorrent began automatically installing a background application called Epic Scale to mine [cryptocurrency](https://en.wikipedia.org/wiki/Cryptocurrency "Cryptocurrency") for the benefit of BitTorrent, Inc., while allegedly giving a portion to charity.[\[50\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-50) Epic Scale mines [Litecoin](https://en.wikipedia.org/wiki/Litecoin "Litecoin") using both [CPU](https://en.wikipedia.org/wiki/CPU "CPU") and [GPU](https://en.wikipedia.org/wiki/GPU "GPU") power, and is classified as "[riskware](https://en.wikipedia.org/wiki/Riskware "Riskware")" by some security programs. A μTorrent developer disputed whether the automatic installation was really automatic, and claimed that as with all other "partner" programs bundled with the software, users could decline the installation.[\[51\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-verge-epicscale-51)[\[52\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-engadget-52)[\[53\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-torrentfreakriskware-53) On 28 March, Epic Scale was removed from the installation and dropped from the list of software bundle partners.[\[54\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-54) Beginning in 2018, advertisements for [Yandex Browser](https://en.wikipedia.org/wiki/Yandex_Browser "Yandex Browser") and other Yandex-produced software were included in Russian and Ukrainian versions of μTorrent.[\[55\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-55) In 2005, an [admin](https://en.wikipedia.org/wiki/Internet_forum#Administrators "Internet forum") on the μTorrent forums wrote: "I don't really know how it's pronounced, I usually say 'you torrent' because it looks like a u". While stating they were not sure, they mentioned that the correct pronunciations for "μTorrent" could be "microtorrent", "mytorrent" (as "my" [\[myː\]](https://en.wikipedia.org/wiki/Help:IPA/Swedish "Help:IPA/Swedish") is the Swedish pronunciation of the Greek letter μ) and "mutorrent".[\[56\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-56) In Greece, where the software was widely used, it is called me torrent,\[[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed "Wikipedia:Citation needed")\] since the letter μ of the Greek Alphabet is pronounced mi in modern Greek.[\[57\]](https://en.wikipedia.org/wiki/%CE%9CTorrent#cite_note-Greek_Alphabet_&_Writing:_An_Introduction-57) The symbol μ is the lowercase [Greek](https://en.wikipedia.org/wiki/Greek_language "Greek language") letter [mu](https://en.wikipedia.org/wiki/Mu_$letter$ "Mu (letter)"), which stands for the [SI prefix](https://en.wikipedia.org/wiki/SI_prefix "SI prefix") "[micro-](https://en.wikipedia.org/wiki/Micro- "Micro-")". It refers to the program's originally small footprint.\[[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed "Wikipedia:Citation needed")\] μTorrent was created and initially developed by [Ludvig Strigeus](https://en.wikipedia.org/wiki/Ludvig_Strigeus "Ludvig Strigeus") ("ludde", from [Sweden](https://en.wikipedia.org/wiki/Sweden "Sweden")). Serge Paquet ("vurlix", from [Canada](https://en.wikipedia.org/wiki/Canada "Canada")) acted as release coordinator, and had intended to work on porting the software to Linux and macOS. He maintained the μTorrent website and forum until the end of 2005 but is no longer affiliated with μTorrent. Since its purchase in 2006, development has been performed by various employees of Bittorrent Inc.; Strigeus is no longer affiliated with μTorrent. \| \| \| \|---\|---\| \| ![](https://upload.wikimedia.org/wikipedia/commons/thumb/5/53/Ambox_current_red_Americas.svg/60px-Ambox_current_red_Americas.svg.png) \| This section's [factual accuracy](https://en.wikipedia.org/wiki/Wikipedia:Accuracy_dispute "Wikipedia:Accuracy dispute") may be compromised due to out-of-date information.
