Hello all,

So I find myself in an odd situation. I upgraded form xp to windows 8.1 on an old laptop I had. Since then, this laptops video card has started to go. So what I am looking to do is to take the hd from that pc, put it in a hardrive caddy, and boot from that on a different computer. For certain reasons I need to retain both OS's.

My question is this. How will Microsoft deal with the licensing in this situation. I attempted this and got a notification that I will need to reactivate windows, but does this count as a second pc in their eyes? Or can I make the call and just say that the hardware has changed.

another note, Ideally I would like to move between both computers without re licensing, but I'm assuming this might not be possible.
