How to Permanently Activate Windows, Office, and Extended Security Updates (ESU)

Microsoft Activation Scripts (MAS) is an open-source activation tool designed to help users activate Windows and Office easily, permanently, and safely. It’s a trusted, community-driven project that uses various activation technologies to support both old and modern versions of Microsoft products — including Extended Security Updates (ESU).

What makes MAS special is its versatility. It offers multiple activation methods, such as HWID, Ohook, TSforge, KMS38, and Online KMS — each built for a specific purpose. Whether you need to activate Windows 11 permanently or renew Office every 180 days automatically, MAS covers it all.

Method 1 – Activate via PowerShell

This is the easiest and fastest activation method, suitable for Windows 8, 10, and 11.

Steps:

1. Open the Start Menu, type PowerShell, right-click, and select Run as Administrator.

2. Copy and paste the following command, then press Enter:

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

3. If this doesn’t work due to ISP or DNS blocking, use this alternative (works on updated Windows 10/11):

   iex (curl.exe -s --doh-url https://1.1.1.1/dns-query https://get.activated.win | Out-String)
   

4. For Windows 7 and later, use:

   iex ((New-Object Net.WebClient).DownloadString('https://get.activated.win'))
   

Once executed, the MAS activation menu will appear. Choose the green-highlighted options to activate Windows or Office. ✅ That’s it — your system will be permanently activated.

Method 2 – Traditional Method (Windows Vista and Later)

If PowerShell doesn’t work, you can use the traditional offline method.

Steps:

1. Download the script file: MAS_AIO.cmd (or the full ZIP package).
2. Run the file as Administrator.
3. The activation menu will appear — select your preferred activation option.
4. Follow the on-screen prompts, and MAS will handle the rest automatically.

That’s all you need to do. In a few seconds, your Windows or Office will be activated permanently.

💡 Tips & Troubleshooting

• Some ISPs/DNS may block MAS domains. → Enable DNS-over-HTTPS (DoH) in your browser to bypass this issue.
• Having trouble running the script? → Use the Traditional Method instead.
• To activate additional products (like Office for macOS, Visual Studio, RDS CALs, or Windows XP), visit the official MAS documentation.
• For unattended activations, MAS supports silent automation.
• Always verify the source before executing PowerShell commands — malicious copies exist with changed URLs. Only trust the official domain get.activated.win.
