When you configure Microsoft Backup to back up your registry, the registry may not be backed up.

This behavior can occur if either or both of the following conditions exist:

•	You are not backing up the Windows folder.
•	All the files that you are backing up are on a drive other than the boot drive.

To resolve this behavior, use the appropriate method:

•	Back up the Windows folder when you back up the registry.
•	Back up at least one file on the boot drive when you back up the registry.

The registry contains several references that are dependent on device drivers and dynamic-link library (DLL) files located in the Windows folder. The registry can not be restored properly without the corresponding Windows folder.
