How To: Change your MAC address in Windows

Although MAC (Media Access Control) addresses were designed to represent a network card’s ID and were designed as permanent, some software and techiques allow us to easily change (or “Spoof”) the MAC address easily.

Change the MAC manually under Windows XP

Method 1

Go the the Ethernet Adapter’s Properties menu, the Advanced Tab and you can see a filed named: “MAC Address”, “Network Address” or “Ethernet Address”, depending entirely on the network card’s driver.

Using this method you can change the MAC address very fast, in a matter of clicks.

Note that some network cards don’t have this featured enabled, but those are rare cases.

Method 2

Another way of changing the MAC Address is modifying the registry.  Press Start, then Run, type regedit then press “ENTER”. Then navigate to the following path: HKEY_LOCAL_MACHINE – SYSTEM – CurrentControlSet – Control – Class – “{4D36E972-E325-11CE-BFC1-08002BE10318}”, where you can find the settings for the network card. The field needed to be modified is “Network Address”.

However, please be advised that to use this method you need Administrator privileges.

Also, for those not familiar with the MAC address, you can find our what’s your mac address by pressing the “Start” button, then Run, type “cmd” and press ENTER. The console window will pop-up in front of you and you can write “ipconfig /all” without quotes. This will show you all the network cards present on the system, with their IP addresses, state and MAC address. The MAC address is called “Physically Address”. The MAC address has the following format:  00-1F-2D-37-C6-3A
