Ghost Generic volume shadow copies back with a vengeance! I thought I had cracked it, however....!
"Devices and Printers" took forever to load which is a symptom of this problem.
So what to do next? In the past 'System Restore' has often been less than reliable so I now use EaseUS Todo which has got me out of trouble on a number of occasions. Therefore I reasoned, "Why do I need VSS (Volume Shadow Copy) at all?".
So, I have removed all the Ghost Generic volume shadow copies and disabled VSS (Control Panel - Administrative Tools - Services - Volume Shadow Copy - double click - change Startup type to 'Disabled'). Now there are no Ghost Generic volume shadow copies and they don't look as though they are coming back.
"Devices and Printers" now loads instantly.
Of course it means that Control Panel - File History - System Image Backup just produces an error message (File History still works OK though). But as EaseUS Todo does what I want, this is not a problem.
I noticed that in the Windows 10 Preview Build 10130, Control Panel has brought back 'Windows 7 Backup and Restore'. I suspect that when Microsoft removed this from Windows 8/8.1, they only did half a job and left all the old Generic Volume Shadow Copies to build up? Just a thought. Perhaps the problem with Ghost Generic volume shadow copies will go away with Windows 10?
Why don't Microsoft sort it out for Windows 8/8.1? It may be an irritation for me but a Google search shows that it is a problem with clogging up and slowing down servers which must be costing for business?
I hasten to add that I am not a Microsoft expert, just a hobbyist. So if anyone has any comments on the above, I would be very interested.
