Windows 10: System restore will not complete

I screwed up and deleted my DNS cache. Now I'm trying to get it back. It's come down to using system restore which will not complete a restore because, it says, it is not finding a file that it needs. I had this problem once before and ended up just giving up on using system restore. I don't know why I can't find the DNS cache with Recuva but I can't. Can anybody bail me out?

Failed to complete System Restore

Hello Passegua,

The error code 0x80070005 may indicate a few things that are causing System Restore Failure. It could be corrupted system files, conflict with other programs such as Anti-virus protection, and etc. As a first troubleshooting step, we suggest
that you perform System restore in Safe Mode. Kindly refer to this link for more information and steps.

Another step that I can suggest is Clean Boot, if the above step fails.

Let us know the outcome.

 

System Restore did not complete successfully.

You might want to try:

• Click on Start button (1). Hold down SHIFT KEY+Click On Power (2) then click on Restart(3)
  
  
  
• The PC will reboot and get into the Recovery Environment
• Click on Trouble Shoot->Advanced Options->System Restore.

I have somewhat the same problem, except that my AV is Windows Defender.
I have a program that will not run and their support system suggested a restore point. However, when I tried to use an existing restore point, after it finished, I received an error message stating that System restore did not complete because an AV program was probably running. I turned off Windows Defender and tried another System restore, only to receive the same error message. Any suggestions?
