Windows has a great utility called System Restore that allows you to revert your system to an earlier state called a restore point. Restore points are created automatically when you install a new app, driver, update, or when you create one manually.

Restoring your PC to an earlier point in time will not affect your personal files, it will only revert system changes and remove anything installed after the restore point was created. Do not turn off or power down your computer during a System Restore to avoid data loss or corruption. If you are using a laptop, make sure it is plugged into power so the battery does not run out during this process.

If your PC has restarted abruptly several times, it will bring up this screen automatically. It can take a long time, over an hour in some cases, for System Restore to complete. When you've exhausted all options in trying to fix a major issue with Windows, you may be left with resetting Windows to its original state your PC had right out of the box.

Depending on the reset method you choose, the process may delete all personal data and apps you have saved on the PC. If you need to back up all your personal data make sure you do so before proceeding. There is no going back, and no chance to retrieve anything removed during the reset process. Please make absolutely sure your backups are up to date before pressing Reset. Windows will guide you through setting it up with your username, password and other basic settings, just like when you first purchased your computer.
