What happen if I use the same Win 8 pro disk and product key ...

[ttan98]

on a second windows 7 machine/hardware? I think I can still install it the software what happen when I try to update the Win 8 pro from Microsoft website?

Anyone knows the answer. I think one windows 8 pro disk supports only one machine. I need to buy another disk for a second machine.

you can use the disk on a thousand of pc if you want , but you can't use the key, you need 1 key / pc. So you just have to buy a key.
