µTorrent was designed with relatively basic system requirements in mind. Machines running any Microsoft Windows operating system from Windows 2000 and newer are able to run µTorrent as well. Support for operating systems older than Windows 2000 has been dropped since µTorrent v2.0.
Users of non-Windows operating systems may be able to use µTorrent on their computers with the use of a special piece of software that allows the operating system to run Windows applications. Note that there are no guarantees of any kind that everything will work properly when µTorrent is used on alternative operating systems.
