You can use a system restore point whenever you want; This process first involves going back into the same System Protection tab listed above. Once you are in this same window and this tab, follow these steps:
- Go to Control Panel, then System and Security, then click System.
- Under the System Protection tab, click the System Restore button.
- When the System Restore utility appears, click Next.
- Select from the list of restore points, which includes the date and time each point was created.
- Click Next.
- Windows also lists any changes that the System Restore tool will undo. Click the Scan affected programs option to see this list. You can skip this step if you don’t want these details.
- Click Finish and confirm System Restore when prompted.
- Your computer will restart and when you log back in, Windows should display a message that the restore was successful.
If your problem is still not solved, consider restoring your Windows to an older restore point – or, if you want to undo the System Restore itself, repeat the steps outlined above, but select Undo Restore system after clicking the System Restore button. If your PC won’t start, you can also use the Windows menu to roll back to a restore point.
Windows may drop into the recovery menu on its own if it can’t boot, but the process is somewhat involved when it doesn’t. If that doesn’t scare you, you can manually access the recovery menu by pressing the power button once or twice while Windows is trying to start. After that click on Troubleshoot, Advanced Options and then System Restore. You can follow the same steps to select and confirm your restore point.
