Editing the Registry Hive For Your Image on the Target Device

  • Article

5/10/2007

You can view and edit the registry hive for your image on your device, before or after you run FBA. The registry files are located in the \WINDOWS\system32\config folder of your target device.

For example, C:\WINDOWS\system32\config.

Before you run FBA, registry files have a .SAV extension. The following list shows the registry hives with the extension:

  • SAM.SAV
  • SECURITY.SAV
  • SOFTWARE.SAV
  • SYSTEM.SAV

When FBA completes, the registry files are saved without the .SAV extension. The following list shows the registry hives without the extension:

  • SAM
  • SECURITY
  • SOFTWARE
  • SYSTEM

For more information about registry hives, see this Microsoft Web site.
