Restore your PC to an earlier point in time
If you think an app or driver that you recently installed caused problems with your PC, you can restore Windows back to an earlier point in time, called a restore point. System Restore doesn’t change your personal files, but it might remove recently installed apps and drivers.
Notes

• System Restore isn’t available for Windows RT 8.1.
• Windows automatically creates a restore point when you install desktop apps and new Windows updates, if the last restore point is older than 7 days. You can also create a restore point manually at any time.

To restore your PC to an earlier point in time

1. Swipe in from the right edge of the screen, and then tap Search.
   (If you’re using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Search.)
2. Enter Control Panel in the search box, and tap or click Control Panel.
3. Enter Recovery in the Control Panel search box, and then tap or click Recovery.
4. Tap or click Open System Restore, and then follow the instructions.
