在界面上，μTorrent直观易用，并支持超过54种语言。

由于其界面简洁，性能和稳定性出众广受好评。

uTorrent is an efficient BitTorrent client for Windows.

Most of the features present in other BitTorrent clients are present in uTorrent, including bandwidth prioritization, scheduling, RSS auto-downloading, and Mainline DHT.

Additionally, uTorrent supports the protocol encryption joint specification and peer exchange.

Unlike many torrent clients, it does not hog valuable system resources--typically using less than 6MB of memory, allowing you to use the computer as if it weren't there at all.
