I recently downloaded and installed CCleaner from the internet and ran the Registry cleaner scan. It reported numerous problems and offered to fix them. I just need some reassurance that fixing these problems won't mess up my computer because I've heard horror stories about computers that have been messed up by bad registry changes. Is CCleaner a trustworthy program?
Before you fix the problems it asks whether you want to save a backup - say yes and it would then be very easy to reinstate if there was a problem. Having said that - in several years of use I have never had to reinstate the registry after use.
I have too used CCleaner for years and have never had any problems, always backup your registry when asked by CCleaner, saying that though I have never needed to restore the registry backup but its always best to backup just in case.
Never had any issues with CC but suspect it's rather "gentle" .... a good thing definitely ... don't get me wrong. See, click here If you export (backup) one of the registry files complete it's of the order of 26mb in size. You do wonder whether a few leftover entries of only a few 10's or hundreds of bytes is an issue at all. Having said that I do run it though :)
