µTorrent is an efficient and feature rich BitTorrent client for Windows sporting a very small footprint. Most of the features present in other BitTorrent clients are present in µTorrent, including bandwidth prioritization, scheduling, RSS auto-downloading and Mainline DHT (compatible with BitComet).

It was designed to use as little cpu, memory and space as possible while offering all the functionality expected from advanced clients. With BitTorrent, you can download files faster and contribute by sharing files and bandwidth.

Additionally, µTorrent supports the Protocol Encryption joint specification (compatible with Azureus 2.4.0.0 and above, BitComet 0.63 and above) and peer exchange.
