My XP Pro registry is corrupted, not caused by Spybot. I did not turn on System restore point. So now my only hope is using registry backup created when you first install Spybot. I remember it took several minutes for Spybot to finished the registry backup job. It probably is a complete backup. If I can get that reg. backup, I think I can restore my system.

I can't find anything related to registry in Spybot --> Recovery.
Please teach me where to look for that registry backup and how to use it.
