I have a Win 8.1 (non pro) retail key which I'm thinking of using to claim Win 10 Home.
I believe OEM keys are tied to one PC configuration, so a change in motherboard / graphics will trigger activation?
What if I activated my retail key on one PC config (say my 4690K machine), then later decided I want to it on my other G3258 PC, would this be OK? How does it work?
