In this article, we will explore the Getmac.exe command-line tool available in Windows 11. Getmac.exe is a useful utility that allows users to retrieve the Media Access Control (MAC) address of a network adapter installed on their Windows 11 system. Understanding how to use Getmac.exe can be beneficial for troubleshooting network issues, identifying devices on a network, and implementing network security measures.

Examples:

1. Retrieving MAC Address of Network Adapters: To retrieve the MAC address of all network adapters on your Windows 11 system, open the Command Prompt by pressing Win + X and selecting "Command Prompt" or "Windows PowerShell". Then, run the following command:

   getmac

   This will display a list of network adapters along with their corresponding MAC addresses.

2. Filtering MAC Address Results: If you want to filter the results to display only a specific network adapter, you can use the "/v" parameter followed by the adapter's description. For example:

   getmac /v /fo list /nh | find "Wi-Fi"

   In this example, the command will only display the MAC address of the Wi-Fi adapter.

3. Saving Getmac.exe Output to a File: If you need to save the output of the Getmac.exe command to a file for further analysis or documentation, you can use the ">" operator followed by the desired file path. For example:

   getmac > C:\mac_addresses.txt

   This will save the MAC addresses to a text file named "mac_addresses.txt" in the root of the C: drive.
