Taken from another post and what helped me with VSS issues:
Please carry out the following steps:
- Open a new Notepad window
- Copy / Paste the below script into Notepad, and save as "vss_fix.reg":
Code:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71a27cdd-812a-11d0-bec7-08002be2092f}]
"UpperFilters"=hex(7):76,00,6f,00,6c,00,73,00,6e,00,61,00,70,00,00,00,00,00
This will update the "UpperFilters" value at this location to be "volsnap" (the hex code decodes to "volsnap"). Once you've copy/pasted the registry key, save this in a location you can easily access (e.g. desktop), and double click on the script to run the fix.
You will need to restart your machine once the fix has run.
