[msicuu2.exe] [351K] Windows Installer CleanUp Utility - This was removed from Microsoft Downloads because it was developed specifically for problems with uninstalling Office. It "sometimes damaged other components"^[1] and better solutions were developed, but this utility is nonetheless useful for other applications. Remember to create a restore point, and treat this as a last (or at least later) resort. You know, like combofix.
