I just now wrote a Windows Tweak to manually change the MAC-Address on your NIC from Windows Registy here. If you thought, its too much to ask then here is a simple tool that exactly performs the steps we performed with a few clicks.

Technitium MAC Address Changer allows you to change Media Access Control (MAC) Address of your Network Interface Card (NIC) irrespective to your NIC manufacturer or its driver. It has a very simple user interface and provides ample information regarding each NIC in the machine. Every NIC has a MAC address hard coded in its circuit by the manufacturer. This hard coded MAC address is used by windows drivers to access Ethernet Network (LAN).

 This tool can set a new MAC address to your NIC, bypassing the original hard coded MAC address. Technitium MAC Address Changer is a must tool in every security professionals tool box. This simple utility can also help with other basic diagnostics like, disable interface, Disable DHCP, Release/Renew IP etc.
