It is still early in the morning here and pardon me if I am not seeing the issue. Could you elaborate on what you want changed and why. This is a guest signature that is stashed away in the hypervisor and perhaps can be retrieved by the host. Other than that, this is not used anywhere else. MSFT has defined a a namespace for guest IDs and while some ranges are reserved for MSFT operating systems, there really is nothing special about the guest ID. Regards, K.
