SMR's Registry Backup Tool

[Govind]

Works with: Windows Vista and Windows 7.

Usage: Makes back ups of your HKEY_LOCAL_MACHINE hive by creating copies of the physical files where the contents of that key are stored.

Cannot be used while Windows is running. You will need to use this in the Command Prompt from the "Repair your computer" option from your Vista/7 install DVD, or if your F8 menu has a "Repair your computer..." option, courtesy of your OEM (press F8 while starting).

Copy this file into C:\Windows\system32\config\BackupRegistry.vbs. You can run this on a non-running Windows installation to make backups of your registry periodically.

If you choose to restore one of the backups you make, go into Windows Recovery Environment, navigate to the folder using Command Prompt, and run the file restore.vbs in that folder.

Wouldn't it be easier just to export the actual registry keys...?

In the case that Windows becomes unbootable due to a registry problem, you can't access the registry of an offline Windows installation through regedit in WinRE.
