Registry cleaner backup?

I've looked thru the various registry cleaner posts but haven't seen this..

What does the Backup piece of the registry backup?

The whole registry?

All the identified clean up items?

Just the items I'm changing?

I'm asking because I run the cleaner and clean up by types. I do the 1st backup but it sounds like I need to do them ALL?

Thanks!

Hi Marjory, and welcome to the forum.

CCleaner backs up the registry entries it removes only, and I think it best to do one "clean" and make a single back up of that operation. I've never came across anyone doing it your way, a bit at a time.

If you ever encounter a problem after doing the registry clean, which back up would you use? It would be impossible to know without knowing the exact cause of any issue.

Hope that helps.
