Microsoft Activation Scripts (MAS):

A Windows and Office activator using HWID / KMS38 / Online KMS activation methods, with a focus on open-source code and fewer antivirus detections.

 

How to Run the Script on Windows 10/11

 

    1. Right-click the Start menu (Windows icon in the bottom-left corner).
    2. Select Windows PowerShell or Terminal from the menu.
    3. In the window that opens, copy and paste the following command:irm https://massgrave.dev/get | iex
    4.  Press Enter to execute.

 

This command uses Invoke-RestMethod (irm) to fetch the script from the specified URL and pipes it directly into Invoke-Expression (iex) to run it.

 

Once the script runs, you’ll be presented with activation options.
Simply follow the on-screen instructions to complete the process.

 

That’s it — you’re all set!
