How to Activate Microsoft Office (Any Version) — A Complete Guide

If you're seeing a persistent "Product Not Activated" message every time you open Word, Excel, or PowerPoint, you're not alone. Many users face this issue—even when they believe their installation is legitimate. Fortunately, there’s a reliable, script-based method to activate any version of Microsoft Office, from 2010 to the latest release, including Microsoft 365.

This guide walks you through a trusted, open-source solution that leverages official activation protocols. The process is quick, reversible, and requires no third-party tools or pirated software.

Understanding the Method

The technique described here uses Microsoft Activation Scripts (MAS), an open-source project developed and maintained by massgrave.dev. It operates within Windows’ built-in activation framework—specifically designed for enterprise environments—and applies it to standalone installations.

Importantly, this method:

• Does not modify system files permanently
• Leaves no lasting footprint on your system
• Can be safely removed at any time
• Uses cryptographic verification to ensure integrity

All scripts are hosted securely and checked against known hash values before execution, minimizing security risks.

Step 1: Open PowerShell with Administrator Rights

Begin by launching Windows PowerShell with elevated privileges.

1. Press the Windows key on your keyboard.
2. Type PowerShell.
3. Right-click on Windows PowerShell and select Run as administrator.
4. Alternatively, press Win + X and choose Windows PowerShell (Admin) from the menu.

Note: Administrator access is required because the activation process interacts with system-level services.

Step 2: Run the Activation Script

With PowerShell open, paste the following command and press Enter:

irm https://get.activated.win | iex

This command downloads and executes the lightweight bootstrap script hosted at get.activated.win, which is the official entry point for the MAS toolkit.

Behind the scenes, the script:

• Verifies PowerShell is running in Full Language Mode
• Checks for interference from third-party antivirus software
• Downloads the latest version of the MAS_AIO.cmd file from trusted repositories
• Validates the downloaded content using SHA-256 hashing to prevent tampering

Step 3: Select Office Activation

Once the download completes, the MAS menu will appear in a new Command Prompt window.

Use the number keys to navigate:

1. Press 2 to activate Microsoft Office.
2. Wait while the script detects your installed version and applies the appropriate activation method—KMS, HWID, or Online activation.

The entire process typically takes under a minute. Upon completion, you’ll see a confirmation message indicating successful activation.

Step 4: Verify Activation Status

To confirm that Office is now activated:

1. Open any Office application (e.g., Word or Excel).
2. Go to File > Account.
3. Under Product Information, you should see "Product Activated" or "Licensed for use".

No watermark, no trial reminders—just full functionality.

Troubleshooting Common Issues

Antivirus Interference

Some third-party antivirus programs may block script execution. If the script fails to run or download files, temporarily disable real-time protection and try again.

Final Notes

While this method provides functional activation, it's important to acknowledge that long-term use of unlicensed software carries risks—especially in professional or networked environments. For continued support, updates, and compliance, purchasing a genuine license remains the recommended path.

However, for personal, temporary, or educational use, this approach offers a safe and transparent way to unlock Office features without cost.
