Restoring from CCleaner

I had my CD-drive messed up (one of the registry files), and was not sure what causesd it. I was going to try and run CCleaner. Is there anyway to back up/recover from CCleaner from the last scan in case this was the problem, and it messes it up (again?)?

Thanks.

If you saved it, yes.

Problem after you've run CCleaner
