Windows 10 Pro Restore Points no longer restore

About 3 weeks ago, I experienced a problem I call "wild mouse," in that the mouse would drag windows around or execute commands without clicking a button. I was able to fix that by cleaning out all the non-Windows startup programs (I haven't figured yet which was the culprit).

But while diagnosing this problem, I tried using Windows Restore to recover to previous restore points prior to the wild mouse problem. I tried several restore points, some originally generated by the system, and some I had stored on a USB hard drive using Windows Backup and Restore.

The restore function seems to start okay, but soon it slows down (a lot). In most cases it eventually would restart the computer. In at least one case it didn't restart, and I had to shut off the computer by pushing the power button for 5 seconds. It would then reboot. Once it restarts, it always leaves this error message:



I tried several restore points. I also tried restoring in Safe Mode. I also decreased the available memory in the System Restore Configure settings so that it deleted some early restore points. Then I increased the memory allotment to make more room, and tried to restore a point again. None of these ideas changed the behavior.

Does anyone have any other ideas on how to make my Windows System Restore work again? I've since bought Acronis, but I'd still like to restore one of my earlier Windows Restore points.

 

I'm getting same thing but my error code is 0x0000043 can't find a solution anywhere on line.

 

I just got this information from the Microsoft Community.

System Restore error 0x80070091

Someone who sent me the link recommended using the 2nd workaround.
