What is it?

Bulk Crap Uninstaller (BCUninstaller) is a Windows program uninstaller designed to remove large numbers of applications with minimal user input. Beyond standard uninstalling, it can clean up leftover files and registry entries, detect orphaned applications, and run uninstallers according to premade lists.

It works with Windows Store apps, Steam games and Windows features, and includes special handling for common installer systems such as NSIS, InnoSetup and MSI (msiexec). Although it targets IT professionals, it is usable by anyone with a basic understanding of how Windows applications are installed and removed.

The project is released under the Apache 2.0 license. It is distributed as a Setup installer, a self-contained Portable build, and a smaller portable build that relies on an installed .NET runtime. Version 6 requires the .NET 8 desktop runtime and targets Windows 10 and later.
