- Completely uninstalled AVG and installed Microsoft Security Essentials.
- Tried turning off System Restore, rebooting, turning it back on.
- Checked the SR schedule in Task Scheduler, all seems fine. It creates restore points just fine, it just won't keep them on reboot.
- Scanned computer thoroughly with three different anti-malware programs, no problems found.
- Did a sfc /scannnow, no problems reported.
No, I'm not running a system with dual booting.
In Local Services, I have Volume Shadow Copy set to Automatic, but it's never started unless I manually start it. I don't know if that's normal or not, have been unable to find a clear answer.
In my event viewer I see many instances of these 2 errors for Volume Shadow Copy - event ID 22:
Volume Shadow Copy Service error: A critical component required by the Volume Shadow Copy service is not registered. This might happened if an error occurred during Windows setup or during installation of a Shadow Copy provider. The error returned from CoCreateInstance on class with CLSID {e579ab5f-1cc4-44b4-bed9-de0991ff0623} and Name IVssCoordinatorEx2 is [0x80040154, Class not registered
].
and event ID 8193:
Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance. hr = 0x80040154, Class not registered.
Please help me - I need to know what the next step(s) should be.
