Upgrade of non-Pro 8.1 from 10 Pro ISO activated on the same hw
I have this riddle to solve: I bought my computer with 7 Pro pre-installed and OEM-activated. I wiped that and clean-installed 8.1 I bought on the side—not Pro, as I wrongly assumed I wouldn’t really need it. Now, however, I’d like to get to 10 Pro on my machine, which is still validly licensed to run Win 7 Pro, so I figured I would re-install 7 Pro on some other disk and upgrade that to Win 10 Pro and have it activate (= register with Microsoft for my machine).
Then I’d go back to my non-Pro 8.1 disk and try to install 10 Pro over it, using DVD from ISO, choosing upgrade. Any educated guess what this would do and whether these steps could possibly go through as intended?
