Microsoft Activation Scripts (MAS)

Last updated May 30, 2026 · Reviewed by KMSAuto.software editorial team

Microsoft Activation Scripts (MAS) is an open-source PowerShell-based activator maintained by WindowsAddict on GitHub. It exposes the same core methods as KMSAuto.software (HWID, KMS, Ohook, TSforge) through a text-based menu instead of a GUI.

Methods bundled with MAS

HWID — permanent digital license for Windows 10/11.
KMS38 — KMS lease set to year 2038 (effectively permanent).
Ohook — permanent offline Office 2016-2024 activation.
TSforge — token-based activation for edge-case SKUs.

How to run MAS

Open elevated PowerShell.
Run: irm https://get.activated.win | iex
Pick an activation method from the menu.
MAS handles the rest in ~30 seconds.

Safety and source

Fully open-source: github.com/kmsauto.software/Microsoft-Activation-Scripts
Every line auditable; no compiled binaries beyond bundled vlmcsd.
Defender flags it as 'HackTool:Win32/AutoKMS' — false positive, expected for any activator.

MAS vs KMSAuto.software

Same activation methods, same upstream code.
MAS: PowerShell menu, scriptable, no GUI.
KMSAuto.software: native GUI, one-click activation, friendlier for non-technical users.
Both produce byte-identical activation results.

Frequently asked questions

▸Is MAS safer than KMSAuto?

Both are equally safe technically. MAS has the edge in transparency because it's fully open-source on GitHub. KMSAuto.software publishes binary hashes for verification.

▸Does MAS contact any third-party servers?

Only for HWID, which contacts Microsoft's activation server (clip.dipper.microsoft.com). No third parties.

▸Can I run MAS without PowerShell?

No — MAS is built on PowerShell. If you prefer a GUI, use KMSAuto.software instead.

▸What is KMS38?

KMS38 is an MAS-exclusive trick that sets the KMS lease to expire in 2038 (Y2K38 limit), effectively making the activation permanent without needing the renewal scheduled task.

▸Does MAS support Office 2024?

Yes. The latest MAS release supports Office 2024 and Office LTSC 2024 via Ohook.

▸Can I use MAS on a Mac?

No. MAS is Windows-only because Windows licensing APIs only exist on Windows.
