I am trying to spoof the MAC address of my new Win7 laptop. To do so I tried specifying an alternate value from the Device Manager which took no effect. I also tried from the registry, as per other threads here, to no avail. Interestingly I also found the registry contained a path 000X\Ndi\params\NetworkAddress\default REG_SZ, but changing that had no effect either :(

I can only guess I share the same issue here: http://forums.anandtech.com/showthread.php?t=2096480 as the wireless adaptor is the same brand bundled with the same operating system. So my question is - is there anything better I can do to achieve a spoofed physical address than rollback the drivers to some older version?

Have you tried turning the adapter off and on again? (Alternatively, reboot.) – grawity May 21 '11 at 19:41
@grawity - several times, both ways. – lpd May 22 '11 at 7:32
@00101010 I installed SMAC and promptly installed after it told me it could only change the mac address to one predefined string unless I paid it forty bucks. The other link specifies it only works up to Vista... I'll give it a go later but I doubt that it'll work unless someone has specifically programmed a way to avoid this extra "security". – lpd May 22 '11 at 7:37
