µtorrent 1.7.7 build 8179 / 1.8 build 11564 RC6

µTorrent 1.7, the BitTorrent client that is..
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 is currently undergoing alpha testing for protocol encryption (to be compatible with Azureus) and peer exchange.
Resource-Friendly
µTorrent was written with efficiency in 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't there at all. Additionally, the program itself is contained within a single executable less than 150 KB in size.
Skinnable and Localized
Various icon, toolbar graphic and status icon replacements are available, and creating your own is very simple. µTorrent 1.7.2 also has support for localization, and with a language file present, will automatically switch to 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
The developer 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 bugs that appear are quickly addressed and fixed.
