pls help me to read the processor id or unique computer id using vb

I was recently trying to do this myself for a business project at work. What I learned was, that the ID was the same for all the chips in my computer lab (same manufacturer). After reading a while, I learned that by default, Intel now has the processor ID disabled. So, in the end, we went with using the MAC address of the network card for computer identification. The only problem is, if they change their NIC card, then they lose their ID also....
