Uninstalling unlisted software
I had a problem today where I need to uninstall an application, but it wasn't listed in Add/Remove Programs.
If you browse to HKLM\Software\MicrosoftWindows\CurrentVersion\Unistall\ in the registry and search for a keyword that will pull up your product, you will find an entry UninstallString. Copy that to the clipboard and then paste it in Run and the uninstall application will begin! MAGIC!
