Windows Uninstaller Benchmarks

Don’t be fooled by marketing claims and pretty promises. See exactly how uninstallers perform.

The latest benchmark

This benchmark study evaluates the performance of various third-party software uninstallers available for the Windows operating system. While many uninstallers make claims about their effectiveness, this benchmark aims to provide objective data about their actual performance.

Windows Uninstaller Benchmark 2026

Revo Uninstaller, Revo Uninstaller Pro, Geek Uninstaller, BCUninstaller, HiBit Uninstaller, Uninstall Tool (CrystalIdea), Total Uninstall Professional Edition, Wise Program Uninstaller Free and Uninstalr were compared.

Three different tests were performed.

Test 1: Portable Software and Leftovers Detection Accuracy

The latest version of Notepad++ portable and Brave Portable are installed. Then, CCleaner is installed and immediately uninstalled using its default uninstaller. After this, the uninstallers are run to see how well they detect the installed portable software and leftovers from CCleaner.

Test 2: Software Uninstallation Accuracy

Adobe Creative Cloud, Discord, Steam and Bongo Cat were installed. Then, they were all uninstalled using each of the tested uninstaller and the system was searched to see how many files, folders, registry entries and registry keys relating to these software were left behind as leftovers.

Test 3: Damaged Software Uninstallation

Corel PDF Fusion was installed and then its uninstaller was deleted. Then, the software was uninstalled using each of the tested uninstaller and the software’s installer was ran again to see whether it still detects the software as installed.
