MAC Address spoofing?

[Spinnaker]

In windows Xp, I've noticed that you can change the mac address of the computer. This made me wonder whether it is just spoofing the MAC address or is it actually changing the MAC address of the NIC, but then I always thaught that a MAC address is unchangable...

I have a problem. See I have a Mac. After I bought my mac I went to the local electronic store looking for some pro games, right. So I asked the guy at the place for some pro mac games. He brang me to a place in store were they had there "Mac Games" The only games were some guittar lesson games and this one "game" called Microsoft Word. If you want to buy a computer whatever you do don't get a Macintosh.
