If you then clean install Windows and try to activate it with the same OEM key, it will fail as the key has already been used and cannot be used on another computer.
Have you considered trying this? Clean Reinstall - Factory OEM Windows 7
Sorry this is so confusing.
I bought a computer with an OEM installation = Computer "A"
I restored an image from Computer "B" to Computer "A"
I activated the OEM key that came on computer "A" on Computer "A" (no hardware change)
but it was not Genuine.
Regarding the clean install, I know this works but it take 4 days to setup our systems from scratch. (We do forensic testing for banks) So we alway using imaging, but we normally don't try using the computer's OEM key on an imported image.
Thanks for your suggestions . . I can always use another Windows 7 key on the image - I was just trying not to use it if the OEM key would work.
