You may want to consider reversing this action using System Restore.
Firstly, restart your computer in safe mode to prevent non windows drivers from loading.
To do this, before the Windows logo screen during bootup, (just after the manufacturer logo screen), click the F8 key.
It will bring you to the Windows Advanced Options Menu.
Use the arrow keys and select safe mode.
Windows Advanced Options Menu Please select an option: Safe Mode Enable Boot Logging Start Windows Normally Use the up and down arrow keys to move the highlight to your choice. |
