Decommissioned OEM keys
I had the same kind of question about a license key from a certain seller with 100%-positive feedback. He is selling OEM keys from "decommissioned" machines, and I do plan to use a motherboard with that same branding but I have a retail upgrade disk I plan to use since I do not have an OEM disk. I explained all of that to the seller and he said it will work, and I do know the folks at Microsoft do try to make activation happen just as often as possible without going beyond the various-and-varied restrictions. I once broke a motherboard and then answered "three" to the question about how many machines had this installation while I was installing on a different board and since my license is from a 3-pack, and then someone on the phone quickly made my activation happen after I had explained what I had done and why.
