How to Activate Windows / Office / Extended Updates (ESU)?

Method 1 - PowerShell ❤️

Open PowerShell
Click the Start Menu, type PowerShell, then open it.
Copy and paste the code below, then press enter.
- For Windows 8, 10, 11: 📌
```
irm https://get.activated.win | iex
```
  If the above is blocked (by ISP/DNS), try this (needs updated Windows 10 or 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:
```
iex ((New-Object Net.WebClient).DownloadString('https://get.activated.win'))
```
- Script not launching❓Use the below-listed Method 2.
The activation menu will appear. Choose the green-highlighted options to activate Windows or Office.
Done!

Method 2 - Traditional (Windows Vista and later)

Download the script: MAS_AIO.cmd or the full ZIP.
Run the file named MAS_AIO.cmd.
You will see the activation options. Follow the on-screen instructions.
That's all.

Tip

Some ISPs/DNS block access to our domains. You can bypass this by enabling DNS-over-HTTPS (DoH) in your browser.

Having trouble❓Visit our troubleshooting page or raise an issue on GitHub.

To run the scripts in unattended mode, check here.

Note

The IRM command in PowerShell downloads a script from a specified URL, and the IEX command executes it.

Always double-check the URL before executing the command and verify the source if manually downloading files.

Be cautious, as some spread malware disguised as MAS by using different URLs in the IRM command.
