Hello.
My question is:
with the WMI i get the serial number of cpu or hard disk.
But i see in the registry and serialnumbers is stored in the registry.
When i get a method from WMI: where the class read the value ???
From the registry or from hardware all times ???

Thank in advance.

The most definitive answer could only be attained using this:

RegMon for Windows v7.04

And even at that, all you can do is rule out the registry method.

Use some basic problem solving techniques: change the value in the registry
to something odd and see what you get.
