When I do the first step, with the Command I have my Nvidia driver back and the message of Activate Windows in right of my screen who disappears.
But when I go to setting for see if my Windows is activated, it say it's not. Any help please ? What I should do !

4 years later and this took of my issues. Upgraded CPU and updated BIOS and get that pesky activation watermark. You're a lifesaver! thought I was going to have to spend $180 on Win Pro again.
