If that really were to happen, it would be an incredably dumb move. It is really simple.. if you don't mind being limited on the number of installs.. buy OEM.. if you pay the ludicrous price for the retail version, you should bloody well be allowed to upgrade your PC as many times as you friggin like. With all of the excessive protection built into windows these days, why the hell would you not be allowed to move it to an upgraded PC. It's not like you could get away with having it run on two PCs simultaneously.

I tend to agree with prime and jared, this will most likely not happen. Just seems like it has bad press written all over it. The licencing is already strict enough, this is the last thing we need. It is really bad when those of us who actually buy the software get the dirty end of the stick
