Jul 28, 2017 - While you can certainly change the MAC address of the network adapter manually through the control panel, there are quite a few software that. Changing the MAC address of the new interface will solve the problem. Similarly, some software licenses are bound to a specific MAC address. Changing the MAC address in this way is not permanent: after a reboot, it will revert to the MAC address physically stored in the card. A MAC address is 48 bits in length.
Technitium MAC Address Changer is a free tool that can change your Media Access Control (MAC) address. Your Network Interface Card (NIC) is hard-wired with a specific MAC address. Technitium MAC Changer can change any Ethernet NIC's MAC address to a specific address or generate a random address. It includes an easy workaround that lets you change the MAC address of most Wi-Fi adapters in Windows Vista and above.
