goto www.sysinternals.com
or www.systeminternals.com
(I can't remember which as I'm at home and am not online as I type this.)
They have a program that will generate a new GUID for your PC. It is marketed as being useful for
folx who clone hard disks for use in equipping an office. Methinks it might be useful for the
paranoid as well.
I'd probably use it at work, but that darned GUID is the token used by NT Domain servers to
authenticate workstations on a domain. The program at sysinternals.com apparently generates a
random one when you need it.
OBCrypto:
I think it would be useful to have one that could generate a specific one as well. One could
distribute the number far and wide to make sure that the number in question would not be of any
use to snoopers. Think I'll ask if they would modify their code to make this possible.

Speaking of which have you guys see:

NT apparently does already do a serial number off your MAC address if you
have a NIC. It's called a GUID. Now last night being curious I ran Regedit
and snooped for everything that said "GUID" and found several of them. Seems
there are lots of these. Anyone know which one is the "real" GUID and what
the others are for?

The easiest way to maximize the amount of information
over a communication line (in the theory's terms) is
to hook up a random noise generator to it.
