Technitium MAC Address Changer is a tool which provides useful information on your network adapters, and enables you to change their MAC addresses to something else.
Why bother? A utility like this can help to improve your privacy when accessing public networks on a laptop, for example (if your MAC address is always changing then you'll appear to be different systems). It can be useful for testing network security, and may have some troubleshooting applications, too.
At a minimum, you can use Technitium MAC Address Changer to find out more about a particular network adapter. Just choose it from the list and you'll see its name, hardware ID, current MAC address and who that belongs to (the card manufacturer, in other words), connection speed, and even a graph showing current network traffic.
And in a click or two you can now also change an adapter's IP address, gateway, DNS server and more.

If you want to change an adapter's MAC address, though, there's the option to create one randomly, enter a particular address of your own, or even choose one from the program's extensive list. The new address can be just for this session, or be made persistent (so it'll survive a reboot), and if you've finished testing then you're able to restore the original address with a click.
There are a few complications involved here which means this process won't always be successful. It worked for us, though, and there is an option you can apply if you have problems (click 'Why' next to 'Use '02' as first octet of MAC address), so if you need to engage in this kind of advanced network tweakery then Technitium MAC Address Changer is a good place to start.

How Does It Work?
This software just writes a value into the windows registry. When the Network Adapter Device is enabled, windows searches for the registry value 'NetworkAddress' in the key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E972-E325-11CE-BFC1- 08002bE10318}[ID of NIC e.g. 0001]. If a value is present, windows will use it as MAC address, if not, windows will use the hard coded manufacturer provided MAC address. Some Network Adapter drivers have this facility built-in. It can be found in the Advance settings tab in the Network Adapter's Device properties in Windows Device Manager.

How To Change MAC Address
- Starting MAC address changer will list all available network adapters.
- Select the adapter you want to change the MAC address. You will get the details of your selection below.
- In the Information tab, find the Change MAC Address frame. Enter new MAC address in the field and click Change Now! button. You may even click Random MAC Address button to fill up a randomly selected MAC address from the vendor list available.
- To restore the original MAC address of the network adapter, select the adapter, click Restore Original button in the Change MAC Address frame.
NOTE: This tool cannot change MAC address of Microsoft Network Bridge. Network Bridge will automatically use the original MAC address of the first NIC added into bridge with the first octet of MAC address set to 0x02.
