Well, when I move licenses around the same key works every time as long as I don't use the key twice while 1 install exists.
Because keys used to forget when you did a "major" hardware upgrade.
Which is why when Microsoft nowadays notices 2 activations for 1 serial they ask "Have you performed any major upgrades to your computer?" instead of just blacklisting the key.
Personally, it's fine to me.
But if you want to be cautious you can always call Microsoft and talk to an individual in India with horrible English and an extremely thick accent.
