Windows 7 to 10 upgrade: Possible activation conflict when selling PC?
I have Windows 7 Ultimate Retail on a PC and upgraded the PC to 10 for free. There is a 10 entitlement based on my 7 license and associated with that PC. While I'm using the free 10 license on that PC, I'm not supposed to be using the 7 license on any other PC (incidentally, what happens if you do that?).
Supposing I sell the hardware, and then install my 7 license on a new set of hardware. Then the person who I sold the old to installs 10, and it will immediately activate because it has a digital entitlement. An entitlement based off of my 7 retail license, which I'm still using on a different machine. Does this mean there will be an activation conflict? Will someone get deactivated or fail to activate? If so, who?
