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:

Open the Start Menu, type PowerShell, right-click, and select Run as Administrator.
Copy and paste the following command, then press Enter:
```
irm https://get.activated.win | iex
```
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)
```

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:

Download the script file: MAS_AIO.cmd (or the full ZIP package).
Run the file as Administrator.
The activation menu will appear — select your preferred activation option.
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.
