I want to know what unique IDs exists in Windows. I can think of the Volume Serial Number:

VOL C:

But this is a 32-bit number and so it is not too hard to have collisions.

There is also the HDD serial number:

wmic DISKDRIVE GET SerialNumber

Are there any other unique IDs?

Note: I know that I can generate my own GUID but this is not what I want.

Neither the volume serial number or the HDD serial number is guaranteed to be unique. – Ken White Jun 05 '15 at 01:52
The industry standard is the MAC address of the onboard ethernet port. (It is *almost* safe to assume that every machine will have one.) – Harry Johnston Jun 05 '15 at 02:11

MAC address is also often trivially changeable (especially in a VM). – nobody Jun 05 '15 at 02:45
@AndrewMedico: which is a feature, not a bug. :-) The system administrator *should* be able to control the ID of the system if necessary. – Harry Johnston Jun 05 '15 at 02:52
