Just recently, I changed the MAC Address of my x64-based PC on Windows 7 by following the steps below :

1. Go to Control Panel.

2. Find Network and Sharing Center.

3. Click on Change Adapter Settings.

4. Then, Local Area Connection appears. Right click and choose Properties button.

5. Click on Configure button and then Advanced tab.

6. Then, the name of Ethernet Configuration button will be displayed.

    example : In my case, NVIDIA Ethernet Configuration.

7. Under a Select Task ...., click on Networking then Adjust Ethernet Settings.

8. Click on button with name : Start configuring networking features.

9. Then, the current MAC address under the variable name "Network Address" will be displayed.

10. To change the value, click on the current value in hexadecimal presentation.

Note: When you change the MAC address, be sure it's a valid address.

Hope it helps...=)
