The Microsoft Activation Scripts (MAS), often referred to as "Activation Script Master," is an open-source collection of scripts designed to activate Windows and Office using various methods like HWID, Ohook, KMS38, and Online KMS.
Below is an informative guide on how the tool works, its primary methods, and how to use it. What is Microsoft Activation Scripts (MAS)?
MAS is a widely used, transparent tool hosted on GitHub that simplifies the activation of Microsoft products. Unlike older "cracks" that often contained malware, MAS is written in batch scripts, allowing users to inspect the code for safety. Core Activation Methods
HWID (Hardware ID): The most popular method for Windows 10/11. It grants a "Permanent Digital License" by mimicking a legitimate upgrade process. Even if you reinstall Windows, the system will remain activated automatically because the license is tied to your hardware.
Ohook: The modern standard for activating Microsoft Office. It works by hooking into the licensing component locally without needing to connect to external servers. It is permanent and supports version 2013 through 365.
KMS38: Designed for Windows versions that don't support HWID (like Windows Server). It extends the activation period until the year 2038.
Online KMS: A traditional method for older versions of Windows and Office. It requires a renewal every 180 days, though MAS can automate this renewal. How to Use MAS (Recommended Method)
The most direct way to run the script without downloading files manually is via the PowerShell command:
Right-click the Start button and select PowerShell or Terminal (Admin).
Copy and paste the following command and press Enter:irm https://activated.win | iex
An interactive menu will appear in a new window. Use the number keys on your keyboard to select your desired option: [1] HWID (For Windows 10/11) [2] Ohook (For Microsoft Office) [3] KMS38 (For Windows Server/LTSC) [4] Online KMS (For older products) Key Benefits
Open Source: The code is publicly available for anyone to audit.
No Antivirus Flags: Since it uses native Windows commands rather than "exe" files, it is rarely flagged by security software. activation script master updated
Lightweight: There is no software to install; the script runs and then closes. Important Considerations
Legality: While MAS is a technical tool, using it to bypass paying for software violates Microsoft’s Terms of Service. It is intended for educational purposes or for users who have lost their original keys.
Clean Versions: Always ensure you are using the official version from the Massgravel repository to avoid modified, malicious versions found on third-party sites.
