As Broni mentioned, Revo is a useful tool, but use with caution.
Although I still have the Free version of Revo installed, I rarely use it anymore. Much safer IMO to use Windows Add/Remove, followed by a manual cleanup and/or the Apps removal tool if one is available.
Revo's follow-up registry scan, like any reg cleaner, can and does make mistakes. Example: On my Vista system, I once attempted to uninstall Windows Live
Mail using Revo, the follow-up reg scan reported ~10,000 reg entries to be deleted. Turned out Revo was also trying to remove Vista's inbuilt Windows Mail (and God knows what else).
It's also probably not a good idea to use Revo to remove software that needs a reboot to complete the uninstall process, as Revo's reg scan may very well delete info that is needed to complete the uninstall during reboot, leaving a lot of junk behind.http://www.wilderssecurity.com/showpost.php?p=1490554&postcount=47http://www.wilderssecurity.com/showpost.php?p=1490589&postcount=48
