Change Network adapter MAC address on Windows 7

Most of us (atleast those who learned computer networking) grew up learning about the 7 layers of OSI ISO model or the simple 4 layer model. The lowest layer is the physical layer. In this layer all machines are assigned an address called the MAC address (Media Access Control Address) . The MAC Addresses come pre-assigned in the hardware and it is assigned by a standard authority so that the MAC addresses does not collide. Most of us thought we cant change it, but yes we can change the MAC address.

To change Mac Address in Windows 7

  • Open Control Panel > Network and Internet > Network and Sharing Center Network Adapter Control Panel Network Settings Windows 7
    Click on Change adapter settings as highlighted in the screenshot above.
  • Right click on your network connection (Local Area LAN or Wireless WAN) and click Properties.
    Network connections windows 7
  • On the properties window click Configure. Local area connection properties
  • On the advance tab, click Network Address and Enter a value (HEX 0-9,A-F) on the right side textbox AAAAAAAAAAAA as shown Advanced Network Properties Windows 7

    If you cant find this option then your network adapter does not support this property.

  • Thats all, To verify goto Command Line and run

    ipconfig /all
    to verify your new Physical Address

    Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Realtek RTL8102E/RTL8103E Family PCI-E Fa st Ethernet NIC (NDIS 6.20) Physical Address. . . . . . . . . : AA-AA-AA-AA-AA-AA DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::3c77:5693:31a2:28a8%11(Preferred)
  • Now the MAC Address on Windows 7 would reflect the one you supplied

Just in case you are not able to connect to internet after this procedure

If you are not able to connect to the internet or other devices revert the changes by clicking on the Not Present Value On advance tab . This can be because your Router is MAC filtered or may be there is a collision with one of the other devices on the network.

Try putting your name as MAC Address

If your name just contains letters from A-F (very unlikely), you can put your name as MAC Address, or just try to make one as close as to your name.

Does it look like DigitalPBK ? :D

  • Hi,
    For changing MAC address in win7 just copy the below text & paste in notepad, save the file with *.reg extension i.e mac-change.reg

    Windows Registry Editor Version 5.00


    Note: In above registry string, the MAC address is "0015D5A53E1E", so you can change it to only Hexadecimal number.
    Hexadecimal No. : 0-9 , A-F

    • Are you changing Wifi or LAN ?

      Mac Address can be changed mostly of LAN adapters only, and dependent on the card manufacturer.

  • Nice Ads

    First, thanks you for the information. You can just right click my computer the click manage. Go to devices and select the adapter then right click and select properties.

    second, I like the googl adsense below. looks like all are ads. :)

  • But Wait, There's Less

    This process works fine for LAN devices, but what about Wireless devices? For some reason Windows 7 only allows MACs with "12" as the first couplet on any Wi-Fi adapter. Figure out a way to get around that, and hordes of networking geeks will be happy to name you king...
