µTorrent is a small and incredibly popular BitTorrent client.
Micro-Sized Yet Feature Filled
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). Additionally, µTorrent supports the ProtocolEncryption joint specification (compatible with Azureus 2.4.0.0 and above, BitComet 0.63 and above) and peer exchange.
Resource-Friendly
µTorrent was written with efficiencyin mind. 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'tthere at all. Additionally, the program itself is contained within a single executable less than 220 KB in size.
Skinnable and Localized
Various icon, toolbar graphic and statusicon replacements are available, and creating your own is very simple. µTorrent also has support for localization, and with a language file present, will automatically switchto your system language. If your language isn't available, you can easily add your own, or edit other existing translations to improve them!
Actively Developed and Improved
Thedeveloper puts in a lot of time working on features and making things more user-friendly. Releases only come out when they're ready, with no schedule pressures, so the few bugsthat appear are quickly addressed and fixed.
