If your computer suddenly becomes unstable due to a problem with your PC, and your PC does not operate normally, you can restore the system to the point in time before the problem occurred.
After restoring the system, you can restore Windows system files, registry, etc. to the previous state. The previous state means returning to “Restore point” generated when installing a new application or driver on the PC, or when updating Windows.
