CHANGING WINDOWS PHYSICAL(MAC) ADDRESS

This is depending on the type of Network Interface Card (NIC) you have. If you have a card that doesn’t support Clone MAC address, then try method 2

METHOD 1

a. Start > Run > devmgmt.msc or Open "Device Manager"
b. Choose your desired NIC under the "Network Adapters" category.
c. Right Click on the selected NIC and choose "Properties".
d. Click on “Advanced” tab.
e. Under “Property section”, you should see an item called “Network Address” or "Locally Administered Address", click on it.
f. On the right side, under “Value”, type in the New MAC address you want to assign to your NIC. Usually this value is entered without the “-“ between the MAC address numbers.
g. Goto command prompt and type in “ipconfig /all” or “net config rdr” to verify the changes.
h. If successful, reboot your systems.



METHOD 2

As you can see the above method is very convenient but not all network cards offer such an option. For example, Broadcom 440x 10/100 ( used in Dell Inspiron 1501 laptops ) does not allow to change its MAC address through the Properties window. In such cases the following method will solve the problem.

1. Go to Start > Run and type regedt32 [NOT regedit] in the box to start the registry editor.

2. Go to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318} and double click on it to expand the tree.

3. Now you can see the subkeys starting with 0000, then 0001, 0002, 0003, 0004 and so on. Each of them represents particular network adapter.

4. Go through each subkey and look for DriverDesc keyword, that matches the network card you want to change the MAC address.

5. Look for a string value named “NetworkAddress”, right click on it and select Modify. Then enter a new MAC address in its value data box. If the value “NetworkAddress” does not exist, then create one with right click on the subkey ( for example 0008 ), then select New > String Value, name the new value as NetworkAddress and repeat the above step.

6. You must restart your computer for the change to take effect.

  1. Manual methods are very effective to change MAC Address of network adapters this is because it doesn't causes any deletion of registry files.
