I've spent a good few hours looking for the solution to this problem. I'm beginning to think that this feature is going to be one of those problems people remember in the future; infamy springs to mind. I started the windows backup and shadow copy services manually without a problem. However, I was naive in thinking this would fix my problem, as I get the exact same error message when I try to do anything in the appropriate control panel area that is in any way related to backing up. I don't understand how I can be denied access to services that are currently running. Before anyone asks, a clean boot is not the solution. I suspect hard drive and/or sub folders' SYSTEM permissions may be the problem. I took ownership of the hidden contents of the windows image and backup folders but to no avail. Any help would be appreciated. Thanks.

Hi, First, I would like to confirm that the detailed error which you received and if it is able to save any files on the other hard disk. Please check the hard disk for errors. Also, this error may be caused by the system image backup configuration on the computer or some related components or services or registry incorrect on the computer, you can follow the below steps to check it firstly: 1. Run “vssadmin list writers” to check if there is any error. 2. Register related dll files (we can ignore error messages if there is any) cd /d %windir%\system32 Net stop vss Net stop swprv regsvr32 ole32.dll regsvr32 vss_ps.dll regsvr32 es.dll regsvr32 stdprov.dll regsvr32 msxml3.dll regsvr32 msxml.dll regsvr32 msxml4.dll 3. Stop related services a) Volume Shadow Copy Service. b) Microsoft Software Shadow Copy Provider. c) COM+ event system d) COM+ System Application 4. Under HKEY_LOCAL_MACHINE \Software\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\Subscript, delete the "Subscriptions" key and leave the EventClasses key 5. Under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VolSnap add MinDiffAreaFileSize (DWORD) and set the value to 3000 6. Restart above services 7. Restart to check the issue.
