Bulk Crap Uninstaller (in short BCUninstaller or BCU) is a free (as in speech and beer) bulk program uninstaller with advanced automation. It excels at removing large amounts of applications with minimal to no user input, while requiring next to no technical knowledge.
It can detect most applications and games (even portable or not registered), clean up leftovers, force uninstall, automatically uninstall according to premade lists, and much more.
Bulk Crap Uninstaller is licensed under Apache 2.0 open source license, and can be used in both private and commercial settings for free and with no obligations, as long as no conditions of the license are broken.
NOTE: Automatic updates are broken for the moment, you will have to download it manually. New version will open the download page instead of automatically updating.
