Fix for System Restore error 0×8007007B in Windows Vista

When you start the System Restore utility in Windows Vista, the following error message may be displayed:
There was an unexpected error:
The filename, directory name, or volume label syntax is incorrect.(0×8007007B)
System Restore will now close.
The same error might occur when running Windows CompletePC Backup.
Cause
This problem seems to affect some OEM systems that have faulty image. Here is an excerpt from The Filing Cabinet Weblog on System Restore error code: 0×8007007B.
This error is caused by faulty imaging by the original equipment manufacturer (OEM) that results in the presence of an invalid volume. To see if this is the problem, go to System in Control Panel and open System Protection. There will be two volumes shown, one of which is selected and named “Missing.” Selecting C:\ and deselecting “Missing” solves the problem.

Resolution

Click Start, type SystemPropertiesProtection.exe. The System Restore Properties window will open.
You may see two C: drives in the listing with the same Volume label (see figure below). Deselect the checkbox for the duplicate volume, and enable the checkbox for the correct drive (the one with Windows logo).
