What is this?
Microsoft Activation Scripts (MAS) is an open-source tool that activates Windows and Office using methods like HWID, Ohook, TSforge, and Online KMS, plus troubleshooting tools for failed activations.
Is this a GUI app or a script I run?
It is a script (PowerShell or a downloadable .cmd batch file) that launches a text menu where you pick an activation method.
How do I run it to activate Windows or Office?
Open PowerShell and paste the provided one-line command, or alternatively download and run the MASAIO.cmd file, then pick a 'Green' option from the menu that appears.
Does it work on older Windows versions too?
It supports Windows Vista and later via the traditional method, and Windows 8.1, 10, and 11 via the PowerShell method.
What should I watch out for when running the command?
Some ISPs/DNS providers block the domains (workaround: enable DNS-over-HTTPS), and you should always verify the URL before running it since third parties have spread malware disguised as MAS by altering the command.
Which Windows versions and editions does this cover?
It targets Windows (Vista through 10/11) and Microsoft Office/Office365, including Extended Security Updates (ESU) activation.
What is TSforge?
TSforge is one of the advanced activation methods bundled in MAS, listed alongside HWID, Ohook, and Online KMS as a way to activate Windows or Office.
What is HWID activation?
HWID is a hardware-ID based activation method included in MAS for permanently activating Windows without needing a key, used alongside the other supported methods.
Can MAS also activate Microsoft 365 or Office?
Yes, MAS activates both Windows and Microsoft Office/Office365, not just the operating system.
How often is MAS updated?
The project is actively maintained, with the README citing version 3.12 released on 04-Jul-2026.
