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:
  2. Run the MAS_AIO.cmd file.
  3. In the menu that appears, type the number corresponding to one of the Green options.

Tip

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.

Changes in This Fork

[9] Turn Off Background Processes - CTT-style optimization

  • One-click toggle in MAS_AIO.cmd that turns off background process bloat, inspired by Chris Titus Tech's Windows Utility:
    • 42 non-essential background services stopped and disabled
    • 22 privacy/performance registry tweaks (telemetry, Bing/Cortana search, Game DVR, activity history, Wi-Fi Sense, Delivery Optimization, ads and suggested content)
    • 15 telemetry scheduled tasks disabled (CEIP, Compatibility Appraiser, error-reporting queue, Maps, ...)
    • Switches to the High Performance power plan
  • Everything is saved to %ProgramData%\MAS_ProcessToggle\state.txt; 2 Turn Processes Back ON restores every service start type, registry value, scheduled task, and your original power plan exactly.

Change Windows Edition improvements

  • New changeable targets: Windows 11/10 LTSC (WNC, EnterpriseS, IoTEnterpriseS) and CloudEdition, with clear warnings where an in-place change is unsupported or irreversible
  • A pre-flight check refuses in-place changes Windows does not support (for example Pro to Home/LTSC) with a plain explanation instead of a cryptic DISM error code
  • DISM/CBS failures are now surfaced instead of being silently swallowed
