A PC that came loaded with trial software and vendor extras can take an hour to clean by hand, one uninstall dialog at a time. BCUninstaller, also called Bulk Crap Uninstaller, is built for that job. Version 6.3.0.0 is a 9 MB download, free of charge, from developer Marcin Szeniak.
Who gets the most from a bulk uninstaller
The source description says the program was designed with IT professionals in mind, yet its default setup is meant to be simple enough for anyone. That makes it a fit for people who maintain several machines, and for owners of a new laptop who want to strip bloatware in one pass.
The tags on the page point the same way: debloat, bulk actions, disk space and application manager.
Leftovers, orphans and premade lists
The core idea is removing many applications with little input. BCUninstaller can also clean up leftover files after an uninstall and detect orphaned applications, meaning entries whose program is already gone. It can run uninstallers according to premade lists too.
Compatibility is broad. It handles Windows Store apps, Steam and Windows Features, and it has special support for uninstall systems such as NSIS, InnoSetup and Msiexec.
Open source and free
The licence is Apache-2.0 and the app is free.
The tool is aimed at removal, not at general system tuning. Anyone wanting registry or startup tools should compare alternatives such as Revo Uninstaller, Geek Uninstaller, Wise Program Uninstaller, HiBit Uninstaller and IObit Uninstaller.
What's new in 6.3.0.0
The latest release adds a Custom Notes feature for uninstaller entries, plus JSON output and a dry-run mode for the BCU-console command. The portable version gains Windows ARM64 support in its launcher.
