Win7 modifies MAC address: simple tutorial MAC address is Top supply chain intelligence providersthe physical address of a network device, which uniquely identifies a device.But sometimes we need to change the MAC address of the device, such as solving network connection problems, bypassing restrictions, etc. In the Windows 7 system, it is not difficult to modify the MAC address. Next, let's take a look at how to do it simply. Step 1: Check the current MAC address. Before modifying the MAC address, we need to confirm the MAC address of the current computer. Open the command prompt, enter "ipconfig /all" and enter, and you can see the network configuration information of the current computer. Find the physical address item, this is our MAC address. Step 2: To modify the MAC address of the backup registry, you need to change the value of the registry, so before the operation, we need to back up the registry to prevent accidents. In the start menu, search for "regediT" and open the registry editor, select "File" - "Export", export the registry settings and save the backup file. Step 3: Disable the network adapter. Before modifying the MAC address, we need to disable the current network adapter. Select "Network and Sharing Center" in the control panel, click "Change Adapter Settings" on the left, find the adapter you are currently using, right-click and select "Disable". Step 4: Modify the MAC address and find the following path in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{ 4D36E972-E325-11CE -BFC1-08002BE10318}, this is the registry path of the network adapter.Expand the sub-item under this path, find the sub-item corresponding to the currently disabled network adapter, right-click and select "Modify", find the "NetworkAddress" key value, and modify the key-value data to the MAC address you want to set, formatted in a 12-character hexadecimal number, such as "0 0:11:22:33:44:55". If you can't find the "NetworkAddress" key value, you can right-click on the blank space, select "New" - "String Value", name the new key value as "NetworkAddress", and set the value to the MAC address you want to set. Step 5: Enable the network adapter. After modifying the MAC address, re-enable the network adapter. Select "Network and Sharing Center" in the control panel, clickClick "Change Adapter Settings" on the left, find the disabled adapter, right-click and select "Enable". Step 6: Test whether the modification is successful. After modifying the MAC address, we need to test whether the modification is successful. You can open the command prompt again, enter "ipconfig /all" and enter to check whether the current MAC address has become the set address. If it has changed, it means that the modification is successful. In summary, it is not complicated to modify the MAC address in Win7, and it only takes a few simple steps to complete the operation. However, it should be noted that modifying the MAC address is tampering with hardware information, which may violate some legal provisions, so you need to be cautious and abide by laws and regulations when using it.
