what does a system restore do on windows 7
System Restore 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 the Windows Server.[1] In Windows 10, System Restore is turned off by default and must be enabled by users in order to function.[2]
Operating system An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. All computer programs, excluding firmware, require an operating system to function.
