Ensure that you have enough free disk space on your system drive (usually C:). System Restore requires some free space to create restore points.
- Open a Command Prompt as an administrator and run the following command:
sfc /scannow
After SFC completes, run this command:
DISM /Online /Cleanup-Image /RestoreHealth
Some antivirus or security software may block or interfere with the creation of restore points. Temporarily disable your antivirus or security software and see if it helps.
