VB.net Unique Hardware ID ideas

Question

I was wondering if there would be anything else I could use in my Hardware ID protection that would make it much more unique.

I am currently using

Processor ID
Volume ID
Mac Address
Graphics Card Name

If you guys can provide source codes to anything else that would make it even more unique please tell me.

Answer 1

I will suggest using the HDD Serial Number instead of the Volume ID.

The Volume ID will change if you format your HDD but the HDD Serial Number will not.
