I bought a Dell 660s from Best Buy, and after getting it up and running, I decided that I did not like Win 8. Bought Win 7 and am currently using. With the release of Win 8.1, I think Id like to try 8 again. I think I can download from the net, but I do not know where or how to obtain the security key for my original Win 8. Posted on the Dell message board, but there seems to be very little traffic anymore.
