When the Network Adapter Device is enabled, Windows searches for the registry value ‘NetworkAddress‘ in the key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1- 08002bE10318}\[ID of NIC e.g. 0001].

If a value is present, Windows will use it as MAC address, if not, Windows will use the hard coded manufacturer provided MAC address.
