how to revert to Registry backups

CCleaner for Windows
1

Can I have some help learning how to recover or re-use the Registry backups that are stored when I run a Registry scan? I see the cCleaner Registry Backups file in My Docs but I don't know how to use them.

Can I try restoring to one or all of them? If I do a restoral and am not happy, can I just restore to the most recent one?

If I restore to an old one done before other registry changes/backups, does it just put the Registry back like it was on that day and so you wouldn't need to restore other changes made since then?

Double-click them.

The backups aren't backups of the Registry, but backups of the keys you deleted ; if you want to restore your Registry to, say, 3 days ago, you'll need to merge every backup from now to days ago.
