This did exactly what I was looking for.

Hi Daniel, I don't know much about CPU serial numbers, but from what I've read they don't exist in modern CPUs. See e.g.:

When I ask for the serial on my CPUs (on linux) I just get "none specified".

It might be possible to get the motherboard serial number, although I haven't managed to get it on Linux without sudo'ing (not a problem on Windows as far as I can tell).

What is it you want to achieve?

Cheers. Ben

This function does exactly what it says it should. Is there a way to pull a serial number from the CPU?
