I have attempted all the standard methods, changing the address, in the adapter's drivers and changing the registry keys. I have only been able to successfully spoof MACs that start with the first two digits as 12. Any other MACs i try to spoof don't work for some reason. There is no error code or anything, the changes just don't take effect. If someone can assist and point me in the right direction to spoofing a MAC in Windows 7, the help would be appreciated.
