Registry First Aid 11.0.1
Description from the publisher
Tired of Windows crashing? Sick of having software lock up on you or taking forever to load? The problem could be all of those incorrect registry entries caused by software installations and un-installations that went awry! Un-installations can leave behind file references in the registry to files that don't exist. You can end up with hundreds of files to slow down your computer and cause software to lock up, requiring a reboot of your computer.
