System restore is an important feature in Windows. You can do it for any troubleshooting purpose like after system crash or if some device driver is not working etc.
Ans: To use System restore follows the sequence: Right-click Computer, select Properties > System Protection > System Restore > Next, and choose the restore point you’d like to use.
Windows 7 has the power to sort out the diseased program. Click the new button to ‘Scan for affected programs’. It will tell you which (if any) programs and drivers will be deleted or recovered by selecting this restore point.
