Bulk Crap Uninstaller (BCUninstaller, BCU) is a lightweight, open-source tool built for one purpose: wiping dozens—or hundreds—of programs off a PC with as little clicking as possible. Portable and only a few megabytes, it still finds more software than Windows itself, then sweeps away the leftover files and registry keys that normal uninstallers forget.
What it does best
- Mass uninstall in one go – tick any number of entries and BCU launches every uninstaller in sequence, auto-clicking the wizard screens so you can walk away.
- Deep-clean leftovers – after each removal it scans for orphaned folders, shortcuts, Registry keys, service entries and offers to delete them in a single click.
- Finds “invisible” programs – detects portable apps, Steam/Oculus games, Windows Store packages, Chocolatey installs and programs whose uninstallers are missing or broken.
- Start-up manager – shows which applications auto-start with Windows and lets you disable or remove them without opening Task Manager.
- Smart lists & search – create filters (e.g., “everything older than 2 years” or “all toolbars”) and BCU will auto-select matches; great for cleaning school/office PCs.
Despite the power, the interface is friendly: colour-coded entries, usage ratings, certificate verification and one-click backups keep even beginners safe. If you need absolute thoroughness, switch to “Quiet” or “Manual” modes, drag the cross-hair onto any window to target that app, or export the entire list for spreadsheet work.
Whether you are preparing a corporate image, reclaiming disk space, or simply spring-cleaning a home laptop, BCUninstaller finishes the job in minutes—no bloat, no ads, no cost.
