Bulk Crap Uninstaller

Bulk Crap Uninstaller (or BCUninstaller) is a free (as in speech) program uninstaller. It excels at removing large amounts of applications with minimal user input. It can clean up leftovers, detect orphaned applications, run uninstallers according to premade lists, and much more! Even though BCU was made with IT pros in mind, by default it is so straight-forward that anyone can use it.

BCU is fully compatible with Windows Store Apps, Steam, Windows Features and has special support for many uninstalling systems (NSIS, InnoSetup, Msiexec, and many other). Check below for a full list of functions.

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.

System requirements

  • OS: Windows Vista or newer is recommended. BCU will also work on XP and 2003 with reduced functionality and possibly some bugs. Both 32bit and 64bit versions are supported.
  • .NET: Recommended .NET 4.0 or newer, can run on only .NET 3.5 with reduced functionality.
  • RAM: Around 300MB or more of free RAM.
  • CPU: Doesn't really matter.
  • Free space: 50MB or more.
  • HDD: Anything will work, but slower drives will make scan times proportionally longer.

How can I help?

Please read the note.


Any modern version of Visual Studio should work. You might need to download this and this library separately.

You can’t perform that action at this time.
