Method 1: Right-click the "Network Neighbor" icon on the desktop and select "properties". In the displayed "network connection" dialog box, right-click the "local connection" icon, select "properties". A "Local Connection Properties" dialog box is displayed. Click "Configure" and select "advanced ", select "Network Address" in the "attribute" column on the left (in fact, not all NICs use "Network Address" for the physical Address description ", for example, Intel's network adapter uses "Locally Administered Address" to describe, as long as the "value" option can be found in the right box ), then, select the single option (not "nonexistent") in the "value" in the right column, and enter the MAC address of the NIC in the box on the right, the format is "000B6AF6F4F9 ". Click "OK" to complete the modification.
However, some NICs do not have this option. Do not worry. You can update the NIC Driver first. This option will usually appear after the driver is updated.

Method 2: Modify the Registry

Step 2: Click Start, select Run, and type regedit to bring up the registry.
Step 2:HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Class \ {4D36E972-E325-11CE-BFC1-08002BE10318} \ 0000, 0001, 0002Under the primary key, findDriverDescThe content is the description of the NIC to be modified. For example, the NIC of Intel is described as"The 3Com Nic is described as"3Com EtherLink XL 10/100 PCI For Complete PC Management NIC (3C905C-TX).
Note: The locations of the NIC description options mentioned above are related to the NIC itself and the operating system. Different NICs may appear in different primary keys, and the same Nic may also appear in different locations with different versions of the Operating System (OEM, VOL, or VLK. The task in this step is to find the primary key that contains the NIC description.
Step 2: select the primary key found in step 2, add a string in the right column, and name it "Network Address". The value is set to the MAC Address to be changed, the format is "000B6AF6F4F9 ".
Note: In this step, the task of modifying the physical address of the NIC can be said to be completed. Some NICs need to restart the following to work normally, and some just need a little time to "respond. The following steps are convenient for you to modify the physical address in the future. If you do not need to modify the address again, you can stop here.
Step 2: Add a primary key named "NetworkAddress" under "primary key selected in step 1" \ Ndi \ params. In this case, a "(default) ", set the value to the MAC address to be modified, in the form of" 000B6AF6F4F9 ". If you do not have this string, you can add it yourself.
Note: This step sets an initial MAC address for the NIC.
Step 2: Add a string named "ParamDesc" under the primary key of "NetworkAddress". The function is to specify the description of the primary key of "NetworkAddress". The value can be named by yourself, for example, "Network Address". In this way, the "Network Address" option appears in the Advanced properties of the Network adapter, that is, the new "NetworkAddress" item just added in the registry ", you only need to modify the MAC address here.
Step 2: Add a string named "Optional" under the primary key of "NetworkAddress" and set its value to "1 ", if you select "Network Address" in the Advanced properties of the Network adapter, the "nonexistent" option will appear on the right.
Step 2: restart the computer (not necessarily restart, but depending on the requirements of different NICs. However, there is no error in restarting .), Find the "advanced" option in the first method, and you will find that"Network Address", Which can be used to directly modify the MAC address or restore the original address.
