Hi, I am interested in trying out Windows 7 Ultimate on my machine. I am a bit confused with all of the different methods there seem to be with activating Windows 7. Can anyone please explain to me or direct me to a post explaining everything? I didn't see any sticky posts that were of any help and I think I might not be the only with some questions. 1) What are all the different ways to activate Windows 7? 2) What are the pros & cons of each method? 3) Is there a preferred or BEST method? 4) Is it safe to activate Windows 7 now, before the official launch?
