When you start the System Restore utility in Windows, the following error message may be displayed:
There was an unexpected error: The filename, directory name, or volume label syntax is incorrect. (0x8007007B) System Restore will now close.
The same error might occur when running Windows CompletePC Backup.
Cause
This problem affects especially the OEM systems that have a faulty image. 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
. This opens the System Restore Properties dialog.
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 the Windows logo.

The fix applies to Windows Vista through Windows 10.

This Problem also existed on my new Windows 7 PC. I couldn’t change the SystemRestore Settings, had problems with Shadow Copies and therefor couldn’t backup including all system-image files with Windows 7 integrated backup software.
When deselecting this double drive c: like in the screenshot “automatic restore points” changing the settings for “system restore” worked, but when I backup with system image files, I still got error 0x81000019 “no shadowcopy could be created”.
This work for Windows 7 also great fix thanks
Thank You!
The Fix worked perfectly for the Windows 7 Home Premium and Windows 7 Professional installations on my DELL Laptop and my DELL Desktop respectively.
wow it was real helpful..thanks..
Thanks..Fix worked great for Windows 7 Home Premium
Thank you very much! This worked! I was completely stumped.
I had the same error message in Windows 7 Pro, but I got the error when trying to set the size for Restore Points from 0% to 20%. There were no checkboxes , but protection was turned On for the 2 hard drives listed: one (C:) and one (G:) (Missing). When I turned Off protection for (G:), that one disappeared and I could set the size for (C:) to 20%.
Thanks, brother!
