Bulk Crap Uninstaller vs O&O AppBuster

Bulk Crap Uninstaller (BCUninstaller) is free Windows desktop software for removing multiple applications with minimal user input. It detects registered and hidden applications, portable apps, Chocolatey packages, Oculus and Steam apps, Windows Features, Store apps, and Windows Updates. It usually tries an application's original uninstaller, but also supports forced removal or removal by window, shortcut, or directory. Afterward, it can find leftovers and clean unused or empty folders in Program Files directories. Other tools include a startup manager, application ratings, Regex filtering, and options to browse, filter, and export application data. It verifies uninstaller certificates and can store settings in a single file. Setup, portable, and standalone portable downloads are offered. Version 6 supports Windows 10 or newer; it requires the.NET 8 desktop runtime unless using the portable version. The product is licensed under Apache 2.0 for free private and commercial use, subject to the license terms. The plan is free.
