Windows would not have access to the product key because it is stored
in a variable without EFI_VARIABLE_RUNTIME_ACCESS, so WGA and other
checks will fail, and the user will notice.
(Not sure if it is implemented this way, my test machine lost the
firmware-embedded product key after the mainboard was replaced.)
