Method 1: Use the Win7MAC address modification tool
1, which is only applicable to the MAC address modification of the NIC of the Windows7 system. XP can be used, but did not do any testing.
2, the wireless network card address under some windows7 can not be modified, in theory, you can also use the software to modify.
3, before modifying the MAC address, please start in the start menu - run, enter cmd to open the console, enter getmac to get the original network card MAC and write it down, you can change it later.
4, the software is very simple to use, just select the network card you want to modify in the drop-down list, then enter a new MAC address in the text box, such as EF2d32BC6525 (be careful not to add a bar), then click the modify button modify.
Then run the input cmd to open the console, enter getmac to see if the modification is successful
Method 2: Use the Win7 system's own function to right click on the "local connection" icon, select "ldquo; attribute" , will pop up a "local connection properties" dialog box, click the "Configure" button, select "advanced", select the left column "property" in the "Network Address" (Note: some The network card is called "network address, some use "Network Address", Intel network card with "Locally Administered Address", of course, some network cards do not have this option), and then select the upper one in the right frame "value" The option (not “ does not exist), you can enter the MAC address of the network card you want to change in the box on the right, in the form of “EF2d32BC6525”. Click the “OK” button and the changes are complete.
Method 3: Use Regedit Registry to modify
Step 1, click “ Start & rdquo;, select “ Run & rdquo;, type “ regedit & rdquo; call the registry. In the second step, under the primary key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass {4D36E972-E325-11CE-BFC1-08002BE10318}000, 0001, 0002, look for DriverDesc, the content is 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's network card will be described as &3;3Com EtherLink XL 10/100 PCI For Complete PC Management NIC (3C905C-TX)”
Note: The location mentioned above for the description of the network card appears, and 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 may appear in different locations with different versions of the operating system (such as OEM version, VOL or VLK). The task of this step is to find the primary key that contains the description of the network card.
Step 3, select the primary key found in the second step, add a string in the right column, named "Network Address", the value is set to the MAC address to be changed, the form is "“000B6AF6F4F9” .
Note: At this step, the task of modifying the physical address of the network card can be said to be completed. Some network cards need to be restarted to work normally.
Step 4, in the primary key selected by the first step, select a primary key named "NetworkAddress" under Ndiparams, which will generally generate a <; (default) The string of ” sets its value to the MAC address that you want to modify, in the form of “000B6AF6F4F9”. If you don't have this string, you can add this string yourself.
Note: This step is to set an initial MAC address for the network card.
Step 5, under the primary key of “NetworkAddress” continue to add a string named "ParamDesc", which is used to specify the description of the primary key of "NetworkAddress"; its value can be named by itself, such as “N< Br>etwork Address", so in the advanced properties of the network card will appear "Network Address" option, is just added in the registry of the new item "NetworkAddress", as long as you modify the MAC address here.
Step 6, under the primary key of "NetworkAddress", continue to add a string named "Optional"; the value is set to “1”, then select "Network Address" in the advanced properties of the network card. When the item is selected, the option “There is no existence” appears on the right side.
Step 7, restart the computer (not necessarily restart, but depending on the requirements of different network cards, however, there is no error in restarting.), follow the first method to find the "advanced" option. It is found that there is an option for "Network Address" in the "Properties" column at this time.
Now the reader can directly modify the MAC address or restore the original address.
