SOLVED: Windows 10 Restore Points Missing or Disappeared | How-To Guide | Rescue Digital Media
I recently had a problem where all my restore points in Windows disappeared. When I created a system restore point and restarted the PC, the restore point was gone! I couldn't figure out why this was happening, but after some research I fixed the problem.
In this article, I will write about a few methods that you can try if your restore points are missing in Windows. If you are still having problems with missing restore points, post a comment and I will try to help.
The first thing you can try is to turn off System Restore. How does this help? Well, the backups are stored in the System Volume Information folder. If this folder gets corrupted, you will need to delete it. You can do this by turning off System Restore and then turning it back on.
