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

Method 1 - PowerShell ❤️

1. Click the Start Menu, type PowerShell, and open it.

2. Copy and paste the code below and press Enter.

   • For Windows 8.1, 10 and 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)

Tip

• Some ISPs/DNS providers 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.

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 is trustworthy when manually downloading files.
• Be cautious of third parties spreading malware disguised as MAS by altering the URL in the PowerShell command.
