What information is used for machine fingerprint

When LexActivator computes the machine fingerprint, what info does it use from the system?

I have a customer who intends to swap in/out different hard disks.
So I need to ensure that changing disk IDs will not affect the cryptlex fingerprint.

This is a windows machine.

Hi Francis,

The hard disk is not part of the device fingerprint, so you are good to go.
