Dear Kingz,

Here is what Microsoft has to say:
?An upgrade of the motherboard is considered to result in a ?new personal computer? to which Microsoft® OEM operating system software cannot be transferred from another computer. If the motherboard is upgraded or replaced for reasons other than a defect, then a new computer has been created and the license of new operating system software is required.?
Since the motherboard contains the CPU and is the ?heart and soul? of the PC, when the motherboard is replaced (for reasons other than defect) a new PC is essentially created.?
Microsoft sent a memo to its OEM partners asking them to enforce this new policy, every time they upgrade a computer for a client.
From the Microsoft License FAQ, question 11:
Rather than purchase completely new PCs, my organization performs in-place upgrades to the hardware on many of our computers. We often times only replace the motherboard, processor, and memory. Since the COA is still on the case and the OS is still installed on the hard drive, this computer is still licensed, right?
Generally, you may upgrade or replace all of the hardware components on your computer and maintain the license for the original Microsoft OEM operating system software, with the exception of an upgrade or replacement of the motherboard. An upgrade of the motherboard is considered to result in a "new personal computer."
Microsoft OEM operating system software cannot be transferred from one computer to another. Therefore, if the motherboard is upgraded or replaced for reasons other than a defect then a new computer has been created, the original license expires, and a new full operating system license (not upgrade) is required. This is true even if the computer is covered under Software Assurance or other Volume License programs.

Complicated.

Note that the restrictions only apply to OEM licenses. Owners of *retail* Windows licenses may reinstall on entirely new machines if they want to, again and again, as stated in the EULA. And of course holders of retail Windows licenses can also replace bits at a time, including motherboards. They might have to call in for activation, but there's no grounds for turning them down.
If you buy the retail Windows version, you can transfer it to a new machine.
May I suggest: Linux (Ubuntu, Fedora), Solaris, or, OS X? No product activation nightmares....there is a reason all this free/open source activity is going on, and this is part of it. F/OS covers pretty much everything except gaming....so far.
