Windows 7 Tips: Change MAC Address

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 address modification tool

1, only for the network card MAC address modification of 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, for later change.

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 Modify The button can be modified.

After starting the personality, run the input cmd to open the console, and enter getmac to see if the modification is successful.

Method 2: Use the Win7 system's own functions

Right click on the “Local Area Connection” icon and select “Property” to pop up a “Local Connection Properties”. Dialog box, click the "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 network card with "Locally Administered Address", of course, some network cards do not have this option), and then select the above single option in the right column "value" (not “ does not exist & rdquo;), At this point, 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 the Regedit Registry to modify

Step 1, click “Start”, select “Run”, type “regedit” to bring up the registry. In the second step, under the primary key of HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Class \\{4D36E972-E325-11CE-BFC1-08002BE10318}\\0000, 0001, 0002, etc., look for DriverDesc, the content is the description of the network card to be modified, such as Intel The NIC will be described as “Intel(R) PRO/100+ Management Adapter”, and 3Com's NIC will be described as “3Com EtherLink XL 10/100 PCI For Complete PC Management NIC (3C905C-TX)”.

Note: The location mentioned above for the description of the NIC is related to the NIC 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", its value is set to the MAC address to be changed, the form is "&ldquo ;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.

In step 4, add a primary key named "NetworkAddress" under the primary key selected by the first step, and then the network key will be generated in the right frame. A string of "(default)", set 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.

In step 5, under the primary key of “NetworkAddress”, continue to add a string named “ParamDesc”, which is used to specify the description of the “NetworkAddress” key, which can be named by itself, such as “&ldquo ;N

etwork Address", so that the "Network Address" option will appear in the advanced properties of the NIC, which is the new item "NetworkAddress" added to the registry, and the MAC will be modified here later. The address is fine.

In step 6, under the primary key of "NetworkAddress", continue to add a string named "Optional"; the value is set to “1”, then select "ldquo;" in the advanced properties of the network card. When the Network Address” item is displayed, 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 the restart.), according to the first method to find “ advanced & rdquo; The option can be found in the "Properties" column at this time has the option of "Network Address", you can directly modify the MAC address or restore the original address.

Sometimes the problem of limited Internet access, system verification, etc. 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. A different angle to change, users in need can try to change it.
