How to Change Mac Address in Windows 7

Thursday, January 6th, 2011

I was asked today to go to Sali’s cousin to configure second notebook with Windows 7to be able to use the Lan Internet connection.

So to be able for the second laptop to be able to connect to the internet over the same utp cable, I had to change the second pc LAN device MAC address to be equal to the first PC (the one who already could connect to the internet).

First I needed to get the original MAC address of the notebook which could already connect to the internet, to do so I used the command:

C:> ipconfig /all

The command will list you all the Interfaces on the pc with all their MAC addresses, use the MAC address which is for the Network LAN Interface:

So Here is how I changed the MAC address on the Windows 7:

1. First go to Control Panel, Network and Internet

Control Panel ->

2. Then go to Network and Sharing Center, Change Adapter Settings

Network and Sharing Center -> Change Adapter Settings

3. Next navigate to Local Area Connection, Properties
Local Area Connection -> Properties

4. Now you need to choose the Internet Protocol Version 4 (TCP/IPv4)
Internet Protocol Version 6 (TCP/IPv6)
(Click Over Configure)

5. Now choose Advanced

6. From Property choose Network Address

Property -> Network Address

7. Click on Value

Value -> Enter new mac address

In the field just fill in the 1st notebook’s mac address

Now the MAC address is duplicated from the first notebook to the second one.
The Network Cable when plugged in to either the first or the second PC will be able to provide both the notebooks with internet 🙂
