windows 8 product key
I'm just curious.
On Figure L, Microsoft gives the Windows 8 Pro Product Key. Just wondering, is this product key only applicable (usable) to the PC which was used to purchase the product key? Or will it work instead on another PC? (eg. you decide not to upgrade the recently-purchased Windows 7 PC; but instead, you want to apply the Windows 8 Pro upgrade product key on an older system (eg. Vista or XP) -- or let's say you want to use a different bit version (eg. instead of 32-bit, using 64-bit -- if you're able to get a copy from say another download).
(Is the given product key bit-specific? works only for 32-bit or only for 64-bit?)
