Microsoft Activation Scripts (MAS)

Open-source Windows and Office activator featuring HWID, Ohook, TSforge, and Online KMS activation methods, along with advanced troubleshooting.

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)
    • Script not launching? Use the below-listed Method 2.
  3. In the menu that appears, type the number corresponding to one of the Green options.

Method 2 - Traditional (Windows Vista and later)

  1. Download the script:
    • MAS_AIO.cmd (Direct script)
    • MAS_AIO.zip (If the direct script is blocked by your browser)
  2. Run the MAS_AIO.cmd file.
  3. In the menu that appears, type the number corresponding to one of the Green options.

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.
