Really First time I hear it like that, Many times I change my Bios and my hardware ID did not change, maybe you made it change as you hack your NT 8 program, as far as I experienced , a Normal change on BIOS like under Microsofr UEFI or TPM which causes a lot lockdown have not made my machine ID change. There is only one guy I see change a BIOS UEFI TPM change by hacking it physically and o other beside him done it . maybe your the 2nd one or you are that Guy.
