Revo is great for uninstalling stuff most of the time. I have found some programs that do not show up in Revo, but it does a much better job of getting rid of the files and registry items that don't always get removed when uninstalled. I will say that a lot of software in Windows 7 seems to not leave anything behind anymore, but every once in a while you'll find something that does. If you don't try a lot of software, Add-Remove Programs is fine, but if you try lots of software or are trying to get rid of something that was "accidentally" or "maliciously" installed, Revo is a great tool in the tool box.
