Except, this is not how GUID's are generated under Windows anymore.
Microsoft bowed to preassure and now use a completely random key generation
technique. This was because a reaction to the paranoid people shouting that
Microsoft were attempting to track them via their MAC address. Okay, MAC
address is by no means unique, but it does single out a very small
subsection of users to be pinpointed by MAC address. Basing any GUID code on
MAC address manipulation to gain pseudo random numbers is therefor on shaky
ground.
