MAC Address Spoofing

To change MAC-Address for a Network card in Windows Registry:

1. Click Start – Run, type “regedit”
2. Navigate to

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318]

HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Control
\Class

\{4D36E972-E325-11CE-BFC1-08002BE10318}

3. Under this key, you shoud see numbers in sequence as “0000″, “0001″ and so on. Click on one at a time to check the description of the device to match it with that of your Network Card. In my case (0001)

4. Once found, in the right-pane, look for “NetworkAddress” key value. If you find it, right-click and select modify. Enter the desired MAC-Address as a 12 digit number (all in one, no “space” “.” or “-”)

5. If you don’t find the key, right-click in the rightpane, select “New” – “String Value”. Enter the name as “NetworkAddress”. Now modify and set the desired value.

6. Now, disable and enable the Network card from the ControlPanel – Network Connections.

This should reflect the new MAC-Address on your NIC. Should you choose to go back to the original manufacturer set MAC-Address simply delete the key you just created/modified in the Windows Registry.

You can also use a tool like Technitium MAC Address Changer to change the MAC-Address of your NIC
