I had the same experience and an added feature when installing Getright on my bro-inlaws Thinkpad it literally froze the computer, the keyboard was inoperable after the install and had to do a hard shut down.
When installing s/w only install the program not the addons such as Gator as they task your sanity.
If your brave use Regedit [ms] and RegCleaner to rid the said annoying programs. I've used SystemMechanic w/little help but that depends on the user. Also don't go crazy w/the Registry.
Isn't the Amiga so much easier to deal with.
