I'm surprised it even worked for 2 actually, anything more than 1 should have been impossible.
#WIN 7 PRO KEY UPGRADE#
After that, I've managed to add 2 more copies both also on that original Win 7 key, and both of which not even within the official free upgrade period, which it seems as though they've chosen to not actually end.Įdit: reading a little closer, it looks like his came from the side of an OEM system, and thus would have been an OEM key. If I recall correctly, my second one was also during the free upgrade period, but of course, was an additional use of the key so already questionable for sure. not 7 The first one definitely was expected since it was within the free upgrade period and, well, 1 -> 1 is what was promised. I'm surprised it even worked for 2 actually, anything more than 1 should have been impossible, and that's assuming that the 1 is the original system to which the sticker was stuck. With that information we may be able to figure out why that was the outcome.Įdit: reading a little closer, it looks like his came from the side of an OEM system, and thus would have been an OEM key. I would be curious to know the details surrounding any case where it doesn't work. Whether that's 10 or infinitely many or some other number, I can't say. Until that happens though, theoretically, as crazy as it seems, you should be able to get "a large number" of Win 10 copies out of an older key. If any of these were to cease, the system would not work. The activation/upgrade must generate a new OEM Win 10 key for the machine the upgrade was done on, rather than using or being tied to the upgraded key in some way.This is something Microsoft could stop at any time, but as far as I know it's still available. The free upgrade must still be offered.This means it can be used on any (one) computer, not just the specific computer it came with. The original Win 7 or 8 key must be "retail", not "OEM".Basically, there's 3 key components to activating like this: I'm sure different people will have different experiences, but so far what I've experienced is inline with my understanding of how it works.

Not saying it doesn't work but that is probably why NZgamer only got it to work on two.Ĥ not 7 The first one definitely was expected since it was within the free upgrade period and, well, 1 -> 1 is what was promised. Oh ok, that could explain how you got in on 7 machines at once.
