uTorrent is one of the most popular torrent downloading programs based off of BitTorrent. It was designed to use minimal resources. Video tutorial available.
It\\\'s a torrent client we have used for years and gave up on it in July 2017. It has become more bloated over the years than originally planned but remains a good choice. Because it is Ad-Supported, sometimes you need to be careful during the install to decline additional software. Ads are now displayed in the program itself. As long as you can get past that, it\\\'s still a good choice used by millions. More recently it crashed our computers with a driver error for a wireless network card we don\\\'t have.
Here\\\'s more in this video on using Utorrent as well as torrent files in general.
