How to change MAC address of the system

Steps to change MacAddress of PC

1. Note down the description and current MAC address of the card you want to modify.
To do this, open a command prompt and type the following:

ipconfig /all

3. Start the registry editor by using regedit command in run(regedit under Windows XP, Windows 7, Windows Vista and Windows 2003 server) and open the node

HKEY_LOCAL_MASHINE\System\CurrentControlSet\Control\Class\
{4D36E972-E325-11CE-BFC1-08002BE10318}

Click on each of them until you get Network adapter in description as shown below:

4. Find the node which contains the field Driver Description in the right pane that matches the description of the network adapter you want to change.

5. Now find the registry key "NetworkAddress" (without quotes). If not found create the new one and choose type String key by right clicking there.


6. Double click the entry "NetworkAddress" and enter the new network address. Note that the new network address should have exactly twelve digits like 001122334455

Right click the network connection you have just modified, and then click disable. After the device has been disabled, right-click the connection again and click Enable.

8. Open a command prompt, and type ipconfig /all to check, whether the new MAC address has been changed. If the displayed physical address is still the same, your network card is probably incapable of changing this setting.
