Short of calling Microsoft (probably what I'll have to do) and convincing them that nothing underhanded is going on, is there any way to swap the Win 7 Pro key I activated on my laptop and the Win 7 Ultimate key I activated on my desktop? Basically, I want to deactivate both and then use them on the opposite machine. I know the key is tied to a hardware signature, so, I can't just change the key, but, I want each key associated with the machine other than the one on which it is now activated. I want Ultimate on the laptop. Both keys were purchased.
