!!! Unique identifier under Windows !!!

Hi there,

How can I get an unique identifier for a PC under Windows?
This identifier should be globally unique (like the ethernet-address of a NIC).

It should be independend of a NIC, as my program should work on standalone-PC's too!

========== AddOn ==========

Could it be possible to get at least the BIOS-version number of a PC? Or what about the harddrive serial-number, how can I get that?

This question has been discussed but no solution is found out.  Someone tries to get the CPU id but it seems that it is not practical.

BIOS serial number is not unique.  Best thing you can do if you don't have a NIC is using the volume serial numbers of the hard drive partitions, which is pseudo-random.  Check the GetVolumeInformation() function.
