What Is Microsoft Activation Scripts (MAS)
Microsoft Activation Scripts (MAS) is an open-source project that provides reliable activation methods for Windows and Microsoft Office. It is widely used by system administrators, IT professionals, and lab builders who need a fast, repeatable activation process.
Key characteristics:
- Open-source and publicly auditable
- Supports multiple Windows and Office versions
- Designed for automation and repeatability
- Commonly used in test labs and rebuild scenarios
MAS bundles several activation techniques and presents them through a simple, menu-driven interface.
Important Considerations
Before using MAS, it is important to understand the context in which it should be used:
- Ensure you are complying with your organization’s licensing policies
- MAS is often used in lab, evaluation, or recovery scenarios
- You are responsible for how and where it is used
This article focuses on how to use the tool — not licensing interpretation.
How to Run Microsoft Activation Scripts
MAS is executed directly from PowerShell using a secure download-and-run method.
Step 1: Open PowerShell
Open PowerShell as Administrator.
Step 2: Run the Activation Command
Execute the following command:
irm [https://get.activated.win](https://get.activated.win) | iex
What this does:
- Downloads the latest MAS launcher
- Executes it directly in memory
- Presents an interactive menu
No files need to be manually downloaded or extracted.
Using the MAS Menu
Once launched, MAS presents a text-based menu allowing you to:
- Activate Windows
- Activate Microsoft Office
- View activation status
- Select different activation methods
Follow the on-screen prompts to choose the appropriate option for your system.
The process typically completes in seconds.
Verifying Activation
After activation completes, you can confirm status by:
- Checking Settings → System → Activation in Windows
- Running activation status checks from the MAS menu
Successful activation will be clearly indicated.
Why Administrators Use MAS
System administrators favor MAS because it:
- Saves significant time during rebuilds
- Works well in isolated or lab environments
- Avoids manual key management
- Fits cleanly into automation workflows
For anyone frequently provisioning Windows systems, MAS becomes a practical tool in the toolbox.
Final Thoughts
Microsoft Activation Scripts (MAS) provides a fast and efficient way to activate Windows and Microsoft Office when traditional methods become cumbersome. Its open-source nature and simplicity make it especially attractive for lab environments and administrative workflows.
As with any activation tool, always ensure you understand and comply with applicable licensing requirements.
