Revo, Geek, IObit or Bulk Crap Uninstaller: Which Windows Uninstaller to Use
For most people, Revo Uninstaller Free or Geek Uninstaller handles the common job: run the app's own uninstaller, then look for what it left. Bulk Crap Uninstaller is the one for removing many apps at once, and IObit Uninstaller has the broadest feature list but comes with more on the page than an uninstaller. Windows' own Installed apps is enough when you trust the vendor's uninstaller and do not care about leftovers.

These entries come from each project's own page. We have not run a shared leftover test, so there is no ranking by files found, and a higher count would not prove a safer result anyway.
Revo Uninstaller
Revo runs a program's built-in uninstaller, then scans for leftover files, folders and registry entries. Hunter Mode is its distinctive idea: drop a target icon on a window, shortcut or tray icon to uninstall it or manage its automatic startup, which helps when you cannot find a program in the list. The free version also has eight extra cleaning tools.
Its comparison table lists forced uninstall, quick and multiple uninstall, extended scanning, real-time logs, browser extension removal and backups among the paid Pro features. If you want a restore point and registry backup before removal, read that list before you rely on the free version.
Geek Uninstaller
A single small EXE that needs no install, with x64 and ARM64 builds. It offers clean removal after the uninstaller and force removal for broken programs, and it handles Store apps too. The page calls it completely free, and its paid edition is sold as Uninstall Tool by CrystalIdea. For a one-off cleanup on someone else's PC, this is hard to beat.
IObit Uninstaller
It has the longest feature list here: programs, Windows apps, browser extensions, bundled components, leftovers and registry entries, plus a Bloatware Remover, Software Health checks and an install monitor. Its product page also promotes other IObit products, and it is worth checking what Software Health will change before you apply it.
Bulk Crap Uninstaller
Open source and free, and built to remove many programs in one run with little input. It covers Store apps, Steam, Windows Features and installers such as NSIS, InnoSetup and Msiexec, and it can detect orphaned applications. It has a portable build. It shows a lot of technical detail, which is the reason to choose it and also the reason some people should not. The repository notes the project is looking for maintainers, though releases continued into 2026.
What "forced" removal really means
A forced removal deletes what a tool can find when the vendor's uninstaller is broken or missing. Services, drivers, scheduled tasks and shell extensions may stay registered, and a mistaken match can take something that a different app shares. So try the normal route first, and read what to do when an uninstall fails. Before removing registry entries, make sure the tool backs them up, and be wary of a long list of "leftovers" you cannot identify. What apps leave behind shows what is usually there.
Where Mole fits
Mole for Windows's Apps page always starts with the vendor's uninstaller, and it handles leftovers only after that succeeds. Strong matches and an app's own data folders start ticked, other uncertain matches do not, and personal data starts unticked. Files go to the Recycle Bin and registry keys are backed up first. You can uninstall several apps in a row and press Esc to stop before the next one.
It is deliberately narrower than the tools above. A running app that refuses to close can be force-quit, but there is no mode that deletes a program without its uninstaller, and no Hunter Mode. It suits you if you also want the cache cleanup, startup items and disk map in the same window. If you only want an uninstaller, the free tools here will do.
FAQ
What is the best free uninstaller for Windows?
For one app at a time, Geek Uninstaller or Revo Uninstaller Free. For many apps in one go, Bulk Crap Uninstaller. There is no measured winner here, so choose by how you work.
Is Revo Uninstaller safe?
It is a long-running tool that runs the program's own uninstaller first. The risk is the same as with any leftover scanner: review what it selects, especially registry entries, and prefer a restore point before removing many.
Is Geek Uninstaller safe?
It is a small portable program from its own site. Force removal is the part to treat with care, since it runs without the vendor's uninstaller.
Do I need a third-party uninstaller at all?
Not always. Windows' Installed apps runs the vendor's uninstaller. A third-party tool adds value when an app leaves large data behind or will not uninstall normally.
Are leftover registry entries a problem?
Usually not for speed. Microsoft does not support registry cleaners, so remove only what clearly belongs to an app you uninstalled, with a backup. See registry cleaning on Windows.
