Find the MAC, or Media Access Control, address of a computer by accessing the Status window of the Local Area Connection adapter. A MAC address is an unique identifying address designated to the physical parts of any network, and it identifies and registers a specific device on the network.

  1. Find the available network connections on the computer

    The network connections available on a computer can be found through the Network and Sharing Center, which can be accessed through the control panel. Click on the Start button, go to Control Panel, select Network and Internet, and go to the Network and Sharing Center. When Network and Sharing Center opens, click on Change Adapter Settings on the left side of the screen to see the list of all available network connections.

  2. Identify the local adapter

    From the list of all available network connections, find Local Area Connection. This is the connection that utilizes the network adapter of the computer, and it's usually created by Windows during installation.

  3. Find the MAC address

    Right-click on Local Area Connection and select Status. When the status window appears, click on the Details button. This opens the Network Connection Details window. Find the Physical Address in that window; that address is the MAC address of the computer.
