GhostMAC

GhostMAC is a lightweight, open-source Windows application hosted on SourceForge that allows you to easily change (spoof) your network interface card’s MAC address with a few clicks. It is written in C# and works by communicating directly with Windows network services and device driver plugins to temporarily override your burned-in hardware address. How to Use GhostMAC to Change Your MAC Address

Using GhostMAC simplifies the process of MAC spoofing without needing to dive into the Windows Device Manager or Registry Editor.

Download and Install: Download the utility directly from the official GhostMAC SourceForge Page. Run the executable file (you may need to run it with Administrator privileges so it can modify network drivers).

Select Your Network Adapter: Launch the application. You will see a list of your computer’s active network adapters (such as your Wi-Fi card or Ethernet adapter). Click on the one you want to modify.

Generate or Enter a New MAC Address: GhostMAC gives you two choices:

Random: Click the button to automatically generate a valid, randomized 12-digit hexadecimal address.

Manual: Type a custom 12-digit hexadecimal string (using numbers 0–9 and letters A–F).

Apply the Changes: Click the Change or Apply button. The tool will briefly cycle or restart your network connection to force Windows to recognize the newly spoofed address.

Revert to Default: If you experience connectivity issues or want to restore your computer’s real hardware address, open GhostMAC again, select the adapter, and click Restore Original. Alternative Ways to Change Your MAC Address

If GhostMAC is unavailable, throws an error, or you prefer not to use third-party software, you can change your MAC address natively in Windows: Method 1: Via Windows Device Manager Press Win + X and select Device Manager. Expand the Network adapters section.

Right-click your current Wi-Fi or Ethernet adapter and select Properties. Navigate to the Advanced tab.

Look for Network Address or Locally Administered Address in the Property list.

Select the Value radio button and type a new 12-digit hex string (e.g., 021122334455). Click OK. Method 2: Third-Party Alternatives

If you prefer an updated tool with a similar graphical interface to GhostMAC, the Technitium MAC Address Changer (TMAC) is a widely trusted, freeware alternative that handles advanced routing and modern Windows 11 updates seamlessly. How to Verify the Change

To ensure your MAC address was successfully changed, open the Windows Command Prompt (cmd) and type:getmac or ipconfig /all
