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, it can be used by anyone with a basic understanding of how applications are installed/uninstalled in Windows.

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.

What are the different variants?

Nightly builds

If you want to get the latest features and fixes as soon as they are available, you can download a nightly build from the actions page.

System requirements

BCUninstaller v6

To get this version download the latest release from the links below.

*Note: Since none of the supported systems have x86 versions, v6 releases no longer include an x86 build. If you need one you can still compile it yourself, or you can use the AnyCPU build instead.

BCUninstaller v5

If you get a DLL error on startup then try running Windows Update. If you get a framework error, install .NET6 either manually or through Windows Update.

To get this version download the latest available 5.x release.

*Note: The Portable version does not require the .NET6 runtime to be installed, since it is included (that's why the portable version is so large).

BCUninstaller v1 - v4

Make sure you have .Net Framework 4.5 installed with all available updates for your system (it is not installed on XP by default).

To get this version compile the legacy 4.x branch or download the latest available 4.x release.

How can I help?

Please check the contribution notes!

Compiling

Development is done on Visual Studio 2022. The solution should just load and build without doing anything extra, provided necessary VS features are installed. The installer is compiled with InnoSetup v6.4. To make a release you have to first run the publish.bat script.

What is this?Bulk Crap Uninstaller (BCU) is a free, open-source Windows uninstaller built for removing large amounts of applications with minimal user input. It also cleans leftovers and detects orphaned apps.
Is this a regular Windows program with a graphical interface, or a command-line utility?It's a Windows desktop application with a graphical interface (built with Windows Forms), not a command-line utility or a web service.
Do I need to install anything else first, like .NET?Version 6 needs the .NET 8 desktop runtime, but you can skip manual setup: the installer adds it automatically, and the full Portable build ships with it (which is why it's so large).
Will it work on older Windows versions?v6 targets Windows 10 and up and only ships 64-bit builds; for Windows 7 SP1 use the 5.x release, and the legacy v1-v4 versions even ran on Windows XP.
Is it meant for IT pros or regular users?Both — it was made with IT pros in mind, but anyone with a basic understanding of how applications are installed and uninstalled in Windows can use it.
Can I use it at work, or is it for personal use only?It's licensed under Apache 2.0 — free for both private and commercial use with no obligations, as long as the license conditions are respected.
What can it uninstall besides regular desktop programs?It fully supports Windows Store apps, Steam games and Windows Features, and has special support for many uninstalling systems like NSIS, InnoSetup and Msiexec.
Can I automate uninstalls instead of clicking through apps one by one?Yes — that's the point: BCU can run uninstallers according to premade lists, so whole batches of applications get removed with minimal user input, including unattended uninstalls.
Is the project still actively maintained?The README opens with a 'Looking for maintainers' warning, but nightly builds with the latest features and fixes are still published on the actions page.
