I've never tried to clean up the Registry on my older Compaq (Win XP) but all programs are getting pretty slow starting up, so I figured it's getting time to start a little lite trouble shooting. I checked the Registry with a program called Easy Cleaner, which found 166 invalid entries. I'm reluctant to do anything with the registry, so questions, Should I remove all invalid entries? If not, how do I know which ones not to remove? Or should I just not let a program like Easy Cleaner mess with the Registry?
