The MAC address, also known as the physical address and hardware address, is used to define the location of the network device. In general, the MAC address is fixed in the network card, but it is not excluded that someone manually modifies their own MAC address. In fact, the method of modifying the MAC address is very simple, can be modified by hardware, or can be modified by software, then how to implement MAC address modification under windows7 system?
Windows7 change MAC address:
Method 1: Use Win7MAC The address modification tool
1 is only applicable to the NIC MAC address modification 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.
Start after the personality, run the input cmd to open the console, enter getmac to see if the modification is successful.
Method 2: Use Win7 system's own function
Right click on the “Local Connection” icon and select “Property” to pop up a “Local Connection Properties” dialog box, click “Configure” button, select "Advanced", select the left column "Properties" in the "Network Address" (Note: some network cards are called "network address, some use" "Network Address", Intel The network card uses "Locally Administered Address", and of course some network cards do not have this option), and then selects the above single option in the right column "Value" (not "<; does not exist"), which can be on the right In the box, enter the MAC address of the network card you want to change, 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 HKEY_LOCAL_MACHINESYSTEM CurrentControlSetControlClass {4D36E972-E325-11CE-BFC1-08002BE10318}000, 0001, 0002 and other primary keys, 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.
The following steps are for the convenience of modifying the physical address later.
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 of "Network Address" in the "Properties" column at this time, and the MAC address can be directly modified or the original address can be restored.
Sometimes Internet access restrictions, system verification and other issues can be solved by changing the MAC address. The method of changing the MAC address under Windows 7 system is actually very simple. The three changes mentioned above are from three different methods. If the angle is changed, users who need it can try to change it themselves.
