Undo System Restore
If you tried using System Restore to fix a problem, but the problem remained or other problems were introduced, you can undo the restore operation in most cases. After you undo System Restore, you can try using a different restore point.
If you use System Restore when the computer is in safe mode, you cannot undo the restore operation. However, you can run System Restore again and choose a different restore point, if one exists.
Open System Restore by clicking the Start button . In the search box, type System Restore, and then, in the list of results, click System Restore.
If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
Click Undo System Restore, and then click Next.
Review your choices, and then click Finish.
Your computer will restart, and then you'll see a confirmation that the undo process has completed.
