I recommend using WMI to obtain the BIOS serial number because all the
values recommended by you and Isabelle (thus far) can be
edited/changed. The only way to change the BSN is to replace the
motherboard. In the case of a clone machine returning an empty BSN, I
substitute with a hash value of that empty string via SHA256. When this
is combined with make & model it serves well enough for my purposes.<g

I agree with what you have written in terms of identification of a specific
machine. However, the OP requested a method for obtaining the "Host ID".
The various definitions I have seen for Host ID have been satisfied by the
MAC address (or IP address) in Windows machines. I believe that is also the
case for Unix machines (see hostid command).

No argument! The MAC address can be edited/changed and so if this
occurs it will break the methodology the OP is trying to implement.
