Much like this guy:

I'm interested in learning when the UUID that is retrieved from
Win32_ComputerSystemProduct.UUID will change.

I want to be able to query WMI for something that is unique and will
not change.



Please help.


Thanks,

Matt

a MAC Address is usually stable and unique but you can remove a NIC...

I suggest just asking the OS to construct a GUID and then store that in
a known location.
Writing your own value should guarantee that it will never change. If
you feel the need,
make two values, both with a checksum digit and string them together...
it'll be that much
harder to discern how to alter your number.
