[View source ] µTorrent (or uTorrent and commonly abbreviated as " µT " or " uT ") is a freeware BitTorrent client by BitTorrent, Inc. for Microsoft Windows written in C++ [1] . It gets the " µ " in its name from the SI prefix " micro " meaning one one-millionth and it refers to the program's small footprint. The program is designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as Vuze or BitComet . The program has received consistently good reviews for its feature set, performance, stability, and support for older hardware and versions of Windows. A report showed that µTorrent was the most used BitTorrent client and the second most popular p2p application. [2] 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. [3] . T
