Microsoft Activation Scripts (MAS) — Open-source Windows and Office Activator

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

Activation Methods

Method 1: PowerShell (Recommended)

This method is the most convenient and works on Windows 8.1, 10, and 11.

1. Click the Start Menu, type PowerShell, and open it.
2. Copy and paste the code below and press Enter.

irm https://get.activated.win | iex

3. In the menu that appears, type the number corresponding to one of the Green options.

Troubleshooting the PowerShell method

If the command is blocked: Some ISPs block the URL. Use this command to bypass DNS blocks (Windows 10/11 only):

iex (curl.exe -s --doh-url https://1.1.1.1/dns-query https://get.activated.win | Out-String)

If you receive a TLS/SSL Error (Older Windows): If you are on an old build of Windows 8.1 or 10, run this command before the main command:

[Net.ServicePointManager]::SecurityProtocol=[Net.SecurityProtocolType]::Tls12

Method 2: Traditional (Offline)

Use this method if you prefer downloading a file or cannot use the PowerShell method.

1. Download the script: MAS_AIO.cmd
2. Run the MAS_AIO.cmd file.
3. In the menu that appears, type the number corresponding to one of the Green options.
4. If your antivirus blocks the file, temporarily disable it.

Tips

• Some ISPs/DNS providers block access to our domains. You can bypass this by enabling DNS-over-HTTPS (DoH) in your browser.
• Having trouble? Open the troubleshooting guide.

• To activate additional products such as Office for macOS, Visual Studio, RDS CALs, and Windows XP, see the unsupported products activation guide.
• To run the scripts in unattended mode, see the command line switches reference.

Notes

• 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.
• No password is required for any download on this site.
