I did a full reset of a Windows 8 installation and upgraded to Windows 8.1 via the store (I would have preferred a clean install, but this was the closest I could get). I have noticed that whenever I backup a partition or set a restore point, that I get errors in the Event Log with description

"Details: AddLegacyDriverFiles: Unable to back up image of binary Microsoft Link-Layer Discovery Protocol. System Error: Access is denied."
I'm not sure how serious this error is or what the fix is. Apparently, others have reported this problem without being able to find a solution.
