Change Physical MAC Address in Windows 7

Mac Address or physical address is the unique network (NIC) address for the system. You can change it for administrative purposes. There are two ways to change the Mac physical address one way is from window registry & other from network properties.

1.Change Address in Window Registry

Step 1

In Start menu, type regedit, the system will automatically detect the option & display it.


Step 2

Press Regedit option, system registry editor screen will appear, locate the path



Step 3

On Key expand; you will see numbers 0000, 0001. Clicking on each number will show the device description matches with your network NIC, in any one of following tree numbers you will find network address option. In my case, it is 0009; click Network Address will open an Edit String screen. You can now insert new value for MAC address (12 digit number; with no space & ‘-‘)


Note: If no key is found, right-click & select “New” – “String Value”. Enter the name as “Network Address”and the desired value then press OK button.

2.Change in MAC Address from Network Connections Properties

Step 1

From Start -> Control Panel-> Network & Sharing ->Change Adaptor Settings.  Right click any of the listed connections & select Properties option


Step 2

Connection properties screen will appear then Press Configure button. In Advanced tab, select MAC address option, enter desired address in the value field and press Ok button.


Step 3

Disable & then enable connection / adaptor settings. Start->Run write cmd, in command prompt, write command “ipconfig -all”, the changed physical address will be shown.

    I did all the steps. I even did step 1 & 2. In fact ‘m working at a company I have the password for the wireless network but it’s not giving me internet connection even if in home it my network adapter works perfectly. So I said if i copy the MAC address of the laptop that they gave me in the company to my computer it will work. The physical address is 00-26-B6-5C-AB-3B i am trying to put it on my laptop but it’s not working. What shall I do??
