How to Spoof MAC Address in Windows

MAC spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface on a networked device.

The changing of the assigned MAC address may allow the bypassing of access control lists on servers or routers, either hiding a computer on a network or allowing it to impersonate another network device.

Hackers also spoof their MAC address to make them anonymous in the cyber space. You can always spoof your MAC address but can never change it. Means you can show to the network devices a spoofed MAC address but your actual MAC address always remained the same.

There are various ways of changing the mac addresses. Most of the Network Interface Cards(NIC) have options for it. To check this if your network card have the option for spoofing Network Address or not, follow the below given steps :

1.) Open Device Manger. Right Click on My Computer. Click on Manage. Then Click on Device Manager on left hand side tab. Or Goto Run and type "devmgmt.msc" without quotes. The Device Manager will be opened.
