You know - current computer on Win 7 retail, upgrade to win 10, but then change computers. Is the retail license retained and thus transferable to the new computer or is it tied to the original hardware thing.
I don't have the definitive 'I've done it, it works' answer. But I did get through to MS support, who seem to suggest it should be OK, albeit might need activation assistance (although seemed to be swimming a bit through tech support misunderstanding so YMMV).
