How To Change MAC Address on A Network Adapter on Windows


MAC address, stands for Media Access Control Address, is a unique identifier assigned to a network interface for communications on the physical network segment. You don’t need to change it at all to make your network working, nor does Microsoft provide you an easy way of doing so. But sometimes, you do have a need to change it temporarily to get around some situations that prevent you from accessing the network. And If that ever happens, you may this post useful.

Before we start, check out this post that explains how to find the MAC address on a local or remote Windows computer.

Same as the other tool, MAC Address Changer works on all supported Windows systems with the support for both 32-bit and 64-bit editions.

Behind the scene, both tools just write a value into a registry key to trick the Windows to think this is the valid MAC address bounded to the adapter. When the Network Adapter Device is enabled, windows searches for the registry value ‘NetworkAddress‘ in the following key

 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{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.
