Changing your MAC on Windows XP

There are two ways two change your IP on Windows. The easy way, and the hard way. Ill discuss how to do both of them in this tutorial.

Easy Way:

The first way to change it is, if your NIC (Network Interface Card) supports cloning your MAC Address. If this is the case then you go to.

Start > Control Panel > Network Connections

Right Click on your NIC card and goto properties. Then click the button labeled Configure. It should bring up another form. Click on the advanced tab. You should see under Property "Locally Administered Address" or "Network Address". Click the radio button next to the text box, and type in your new MAC address. (note you do not use the "-" when you enter your no MAC Address.

To check and see if it worked or not go to

Start > Run > and type in "cmd"

When the terminal comes up issue the command.

ipconfig /all
-----------------------------------------------------------------------------------------------------------------------------------------------

Hard Way:

To change your MAC Address the hard way, you first go to

Start > Run > and type in "cmd"

Once the terminal comes up type in

"net config rdr"

It should bring up alot of things, but what you are worried about is

NetBT_Tcpip_{ The Numbers Between here}

Copy the numbers in between there and write it down somewhere, seeing that you will need them later.

After you are done with that go to

Start > Run > and type in "regedt32"

That should bring up the windows registry. Once the registry is up go to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}

Click on the drop down menu and you should see the sub-categories

0000
0001
0002
and so on.

Click on each one and compare the "NetCfgInstanceId" Key with the number you wrote down earlier. Once you find a match double click on the key "NetworkAddress" and change the value to your new MAC address. Hit ok and reboot your system.

Have Fun!
