How to Activate Windows (Any Version) — A Complete Guide

Stuck with the "Activate Windows" watermark or notification? Experiencing limitations due to an unactivated Windows installation? You're not alone. Many users encounter this issue, especially after reinstalling Windows or changing hardware. There's a reliable, script-based method to activate various versions of Windows, from Windows 7 to the latest Windows 11, using an open-source solution.

This guide walks you through a trusted, open-source solution that leverages official Windows 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) or Windows Terminal (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 Windows Activation

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

Use the number keys to navigate:

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

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 Windows is now activated:

1. Press the Windows key + I to open Settings.
2. Go to System > Activation (or sometimes Update & Security > Activation on older versions).
3. Under "Windows activation", you should see "Windows is activated" along with the edition name.

No watermark, no limitations—just a fully functional system.

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 Windows features without cost.
