Revo Uninstaller is an uninstaller for Microsoft Windows. The freeware version of Revo Uninstaller does not find or uninstall 64-bit applications. Revo Uninstaller can also irrecoverably delete files. The freeware version 2 of Revo Uninstaller does now support both 32-bit and 64-bit applications. The toolbar uninstaller does not function, instead re-installing the add-on if manually removed. New features include Duplicate File Finder, System Dashboard, Application Uninstaller, Windows 8 Compatibility. "Cleaning" (Disk Cleaner, Disk Explorer, Duplicates Finder, Uninstaller) and "Optimization" (Context Menu Manager, Startup Manager). The uninstaller blanks out the values, rather than deleting them. While there was no uninstaller, it could be deleted easily if desired. Microhelp published Spreitzer's program as Uninstaller version 1.
