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).
System Restore is a feature in Microsoft Windows that allows the user to revert their computer's state (including system files, installed applications, Windows Registry, and system settings) to that of a previous point in time, which can be used to recover from system malfunctions or other problems. First included in Windows Me, it has been included in all following desktop versions of Windows released since, excluding Windows Server. In Windows 10, System Restore is turned off by default and must be enabled by users in order to function. This does not affect personal files such as documents, music, pictures, and videos.
In prior Windows versions it was based on a file filter that watched changes for a certain set of file extensions, and then copied files before they were overwritten. An updated version of System Restore introduced by Windows Vista uses the Shadow Copy service as a backend (allowing block-level changes in files located in any directory on the volume to be monitored and backed up regardless of their location) and allows System Restore to be used from the Windows Recovery Environment in case the Windows installation no longer boots at all.
