Answer Description
System Restore settings are found in the System Protection tab of the System Properties applet window. System Restore can be used to undo system changes by reverting a computer to a previous restore point. This is helpful if a newly installed application is causing issues (e.g. a buggy driver) or unwanted system configuration changes have been made (e.g. incorrect Windows Registry changes).
