I was wondering which one to get for say 15-20 copies of windows 7. I cannot really find how many copies you get of each. I heard from a friend that Technet is 10 copies of Win7 Ultimate, Business, and Home Premium. Would that be correct? If so, that would be perfect for what I need.
Also how does the system work? Do the keys last indefinitely or only as long as your subscription?
Thanks
