Use System Restore

System Restore is a built-in feature created by Windows. This unique tool allows users to back up their system at a specific time. This way, they can go back to their previous system state at any time if something goes wrong. This is important when troubleshooting problems on your computer. If something goes wrong, you can restore your system to a previous version.

1. Start “Run” by typing it in the search box or by pressing Windows + R on your keyboard. In the “Run” field type regedit and press OK. This will launch the registry editor.
2. Find it in the registry editor and click Computer.
3. Click File on the toolbar at the top of the window. Then select Import. Select the place where you saved the previous backup.
4. click the Open button. At some point, this will restore the system to its original state.

As always, create a system restore point or backup for your device before continuing with troubleshooting methods. This avoids an unnecessary burden of errors that may occur when trying to fix the problem.
