Win7 How to modify MAC address?

method One: Use Win7mac address modification tool

1, only applies to the Windows7 system's network card MAC address modification. XP can be used, but no tests are done.

2, a part of the Windows7 wireless network card address can not be modified, in theory may also use the software modification.

3, modify the MAC address before, please start in the menu-run, input cmd Open the console, input Getmac get the original Nic Mac and write down, for later can be changed back.

4, the software use method is very simple, simply select the network card to be modified in the Drop-down list, and then enter a new MAC address in the text box, such as ef2d32bc6525 (pay attention not to cross bar), and then click the Modify button to modify.

Then run input cmd Open the console, enter Getmac to see if the modification succeeded

　　method Two: Using the Win7 system itself to right-click on the local Area Connection icon , select Properties, pop up a dialog box for local Area Connection properties, click the Configure button, select Advanced, and select "Network Address" in the left column "Properties" (Note: Some NIC is called "The network address, some use" network addresses ", the Intel network card uses" locally administered adress ", of course some network cards do not have this option, and then select the right Column box" value "in the above one single option (not" does not exist "), At this point you can enter the box in the right to change the NIC MAC address, in the form of "ef2d32bc6525". Click on the "OK" button and the modification is complete.

　　Method III: Using the Regedit registry to modify

Step 1th, click Start, select Run, and type "regedit" to bring up the registry. 2nd step, in Hkey_local_machinesystemcurrentcontrolsetcontrolclass {4d36e972-e325-11ce-bfc1-08002be10318}000, 0001, 0002 Wait for the primary key, look for DriverDesc, the description of the network card to be modified, such as Intel's network card will be described as "Intel (R) pro/100+ Management Adapter", 3Com network card will be described as "3Com EtherLink XL 10/100 PCI for Complete PC Management NIC (3C905C-TX) "and so on.

Note: The location of the options mentioned above regarding the NIC description is related to the network card itself and the operating system. Different network cards may appear under different primary keys, and the same network card with different versions of the operating system (such as OEM version, vol or VLK, etc.) will also appear in different locations. The task of this step is to find the primary key that contains the network card description.

The 3rd step, select the primary key found in the second step, add a string in the right column, named "Network Address", whose value is set to change to the Mac, in the form of "000b6af6f4f9".

Note: To this step, the task of modifying the physical address of the network card can be said to be completed, some network cards need to restart the following to normal work.

Step 4th, add a primary key named "NetworkAddress" under the "first selected primary key" Ndiparams, which will typically have a "(default)" String in the right column box, setting its value to the MAC address that you want to modify eventually, in the form of " 000b6af6f4f9 ". If this string is not available, readers can add this string themselves.

Note: This step is to set an initial MAC address for the NIC.

Step 5th, under the primary key of "networkaddress", continue to add a string named "Paramdesc" that specifies the description of the "networkaddress" primary key, and its value can be named by itself, such as "N

Etwork address ", so in the advanced properties of the network card will appear" network addresses "option, is just added in the registry of the new item" NetworkAddress ", in the future as long as the changes in the Mac location.

Step 6th, continue to add a string named "Optional" under the primary key of "networkaddress" with the value set to "1", then the "Do not exist" option appears on the right when you select the "Network Address" item in the advanced properties of the network card.

The 7th step is to restart the computer (not necessarily reboot, but depending on the requirements of the different network adapters, however, there is no error in restarting.) To find the advanced option in the first way, you can see that the "Network address" option already appears in the properties column.

Now the reader can be used to directly modify the MAC address or restore the original address.
