Windows 8.1 Not restoring from a restore point

All of a sudden my computer will not restore from a restore point. I have used it in the past with no problem, but my latest attempt fails and gives the message:

"System Restore did not complete successfully, Your computer's files and settings were not changed.
Details;
System Restore could not access a file. This is probably because an anti-virus program is running on the computer . Temporally disable your antivirus program and retry System Restore.
An unspecified error occurred during System Restore, (0x80070005)

I have disabled Windows Defender real time protection, but System Restore will still not work.

Any help would greatly be appreciated.

Thanks!

Run a malware scan using Malwarebytes Free

Run sfc /scannow in an elevated command prompt

Try System Restore in Safe Mode.

Malwarebytes came up with nothing.

When I ran sfc here is the message I got...

Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.log...

Click Start, and then type System Restore in the Start Search box.
Right-click System Restore, and then click Run as administrator.
In the System Restore dialog box, click Next.
Select a restore point, and then click Next.
In the "Confirm your restore point" window, click Finish.

From the same elevated command prompt, run this command, it will take a while to run.
Dism /Online /Cleanup-Image /RestoreHealth
When completed, run the sfc command again then reboot. Now try

Try running it in Safe Mode.

You may have to Refresh your install, back up your data before doing anything.

Still no dice, a complete reinstall of Windows may be in order.

I had the same problem with SFC /Scannow and I ran the long "DISM" line in the 3rd entry of this thread - that fixed it. Took a while to run.

sfc /scannow not repairing corruptions

Regarding system restore not working: System restore points appear to be saved shadow copies. Twice I have had the shadow copy service stop working, and I found that "Repair Strategy 2" on the following page fixed the problem both times. Unfortunately, it also deletes all saved restore points so use this as a last resort. Note that this page is written for servers so some items may not apply.
