“MAC Address Information”

The MAC address of your network adapter is important and uesful. Should you need to know what it is and / or Change it, read on.

1.Find the MAC address of your network adapter.

A.Use the getmac command in PowerShell, or Command Prompt.
First, open Command Prompt or PowerShell. Then, type in the command “getmac” and press Enter on your keyboard. The getmac command outputs a list of all your network adapters and their MAC addresses, which you can check in the Physical Address column.

B.Use the ipcfg command in PowerShell, or Command Prompt.
First, open Command Prompt or PowerShell. Then, type in the command “ipconfig /all” and press Enter on your keyboard. The command displays all of the current TCP/IP network connections and detailed technical information about each. To find your network adapter's MAC address, identify the network adapter's name from the Description field and then check the Physical Address field, as illustrated in the screenshot below.

2.Change or spoof the MAC address of your network adapter.
Changing the MAC address of a network card is not something most users have to do. However, some users may need to spoof the MAC address of their Windows computer to cope with different problems or network restrictions.
The MAC address identifies the device connected to a network and allows the network to track, restrict or allow access based on it.
For example:
If you need to assign a static IP address, your router identifies and gives the static IP address based on the MAC address. Changing the MAC address comes in handy when it is difficult or cumbersome to change the MAC address rules for your network. As another example, if you change your Windows computer, or only the network card, and your ISP restricts your access to the internet using your MAC address, it’s easy to change the MAC address to the old one and regain internet access just like before the change.
Some software when registered locks to the MAC address.

A.Using Device Manager.
Open the Device Manager on your computer or device. In the Device Manager window, expand the list of Network adapters by clicking or tapping on their entry. Then, right-click or press and hold the network card for which you intend to change the MAC address and select Properties in the contextual menu.

In the network adapter’s Properties window, head to the Advanced tab. In the Property list, select Network Address, and then type the new MAC address inside the Value field on the right side of the window. When finished, press the OK button.

Windows changes the MAC address immediately, but you’ll need to reboot your PC to start using it.

B.Change the MAC address in Windows using the Registry Editor.
Start the Registry Editor as administrator and use its address bar or its navigation panel on the left to get to this path:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}
as illustrated in the screenshot below.
Underneath this node, you should see the list of all the network interfaces found on your Windows PC. Browse through them and check the information displayed on the right panel to identify the one you need to change. The DriverDesc field is the most likely to help you pinpoint the right network card.

Right-click or press and hold on the network card node in the left panel, choose New, and select String Value in the contextual menu.

On the right panel, type in NetworkAddress as the name of the newly added string value. Then, double click or double-tap to edit the NetworkAddress.

In the Edit String window, type in the new MAC address that you want to apply to your network card.

Finally, press OK and restart your computer to start using the newly set MAC address.
Changing or spoofing the MAC address is not a common intervention. The security behind the MAC address is relatively poor because, as you’ve seen, it is easy to change it to any value you want.
Warning::
Keep in mind, though, that you cannot have two devices with the same MAC address active at the same time in a network.
