Rolling back OS (Win7 Pro to Home Premium)
My school gave us subscription to DreamSpark and the ability to upgrade our home machines. I decided to try out Windows Professional on my Alienware laptop and after the activation period was up I found out that the key doesn't work that I was given and they won't give me another key saying that they had already given me one. So I just want to turn the clock back to my installed version that came with the laptop of Home Premium and quit having to see that stupid "Activate" sign and have to re set up my desktop every time I log in. Is there any easy way to do this?
