System Restore is must have feature for any OS that allows the user to revert their computer’s state (including system files, installed applications, and system settings) to that of a previous point in time, which can be used to recover from system malfunctions or other problems.
Sometimes installing a program or driver can make your OS go to blank screen. System Restore can return your PC’s system files and programs to a time when everything was working fine, potentially preventing hours of troubleshooting headaches. It won’t affect your documents, pictures, or other data.
