How to Undelete Deleted Registries

The System Restore utility is a Windows tool that can be used to undo changes made to a computer's system settings. Since registry keys are a part of a computer's system settings, you can use the System Restore utility to undelete deleted registry keys. System Restore works by periodically taking "snapshots" of a computer's Windows system settings. These snapshots, called "restore points," may then be used to "turn back time," and undo changes made to a computer's system settings
