Free utility to spoof MAC address instantly

Technitium MAC Address Changer allows you to instantly change (spoof) the Media Access Control (MAC) address of your Network Interface Card (NIC). The user interface is very simple and provides a wealth of information about each NIC in the machine. Each NIC has a MAC address hard-coded into its circuit by the manufacturer. This hard-coded MAC address is used by Windows drivers to access the Ethernet network (LAN). This tool can assign a new MAC address to your NIC, bypassing the original hard-coded MAC address. Technitium MAC Address Changer is an essential tool in every security professional's toolbox.
