Three ways to modify Win7 MAC address

Method One: Using the WIN7MAC Address Modification tool 1, only applies to the Windows7 system's NIC 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.

Personality after starting, run input cmd Open the console, enter Getmac to see if the modification succeeded

Method Two: Using the Win7 system itself function in the "Local Connection" icon right click, select Properties to 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 cards are called " The network address, some uses "network addresses", the Intel network card uses "locally administered address", certainly also some network card does not have this option), then selects the right column box "value" 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.

The 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. The following steps are intended to later modify the physical address for convenience.

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, such as "Network Address", This way in the advanced properties of the network card will appear in the "Network Address" option, is just added in the registry of the new item "NetworkAddress", as long as the changes in this MAC addresses can be.

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 bar, and readers can now use it to directly modify MAC addresses or restore their original addresses.
