I started to upgrade all my drivers since I downloaded windows 10. Everything was going along fine until I hit the driver on my mouse. Gone the mouse disappeared. There was no way to get it back. So I finally hooked up another mouse and tried to go back and roll back the driver to the other version. Having trouble. Its says it has to be in administration to do so. I don't think it is but I had computer people helping me and no luck. So can this be done. The roll back box won't lite up and it has to be lite to be able to roll back. Any help would be great. Thanks
