Uninstall Cleaner actually cleans up after the uninstallers. While you would think that Windows doesn’t need a cleaner for the uninstaller (well, maybe you would think so), it does. Sometimes uninstallers fail to clean up certain parts and thus bomb out. They do remove the application, but fail to do the remaining part which is remove the entry from the registry. This cleaner will go and find the dangling registry entries and remove them. Pretty nifty and very much a directed product specific to one purpose.
