Zitat aus obigen Link:
"OEM software is also
tied to the motherboard it is first installed on. Unlike the retail versions of Windows which can be transferred to a new computer, OEM versions are not transferable. What about upgrading hardware? Microsoft says that anything is fair game, except the motherboard. Replacing the motherboard in a computer results in a "new personal computer," which the company considers to be synonymous with a transfer. It's not permitted with an OEM edition of Windows."
