We can try the following steps and check if it works for you.

Run System Restore in Safe Mode

The first method to troubleshoot System Restore issues is to run System Restore in Safe Mode. To start Windows 10 in Safe Mode:

Press Windows Key + R to load the Run dialog box.

  • Type “msconfig” and press Enter.
  • Click the Boot tab and enable the Secure Boot option.
  • Click OK and restart your computer.
  • Note. To restart Windows in Normal Mode, you must disable Safe Start in the same way.

Check system security settings

Your Windows system protection settings may be corrupted, and System Restore may cause a “System Restore Failed” error.

To ensure that your system’s security settings are correct, follow these steps:

  • Start Windows
  • Click Start
  • Right click on computer
  • Click Properties
  • Click System Protection
  • Make sure the hard disk is set to On in the Security column. If the value in the Protection column is disabled, select the hard drive and click Configure.

Disable Antivirus

If you are using antivirus software, disable it.

In most cases, System Restore will not complete successfully because the antivirus program is already running on the computer and System Restore is trying to use a file that is also used by the antivirus program.

Start SFC Analysis

The SFC utility reports any corrupted system files that may have caused the system restore to fail.
