MAS vs KMSAuto — การเปรียบเทียบ 2026

Same methods, different delivery

Both MAS and KMSAuto.software expose HWID, KMS38, Ohook, TSforge, and Online KMS. The end result is identical — a licensed Windows or Office install. What differs is how the script reaches your machine and whether the internet is required at runtime.

MAS: online-first PowerShell launcher

MAS auto-updates every time you run the one-liner because the launcher fetches the latest modules from kmsauto.software. This is ideal for connected machines on relaxed ExecutionPolicy.

• Requires internet at runtime
• Requires PowerShell with relaxed ExecutionPolicy
• Always the latest build
• View source: github.com/kmsauto.software/Microsoft-Activation-Scripts

KMSAuto.software: offline single-file .cmd

KMSAuto.software is a single audited batch script. Copy it to a USB stick, boot an air-gapped lab machine, and activate without ever touching the internet.

• Works 100% offline
• Single plain-text .cmd, openable in Notepad
• Pin a specific version forever
• Best for air-gapped, hardened, or restricted hosts

When to pick which

If your machine has internet and you want auto-updates, MAS is great. If you need offline, air-gapped, or hardened-host support — or you simply want a single file you can audit in Notepad — pick KMSAuto.software.

Safety

Both projects are open source and reviewed by the activator community. Defender flags both with the generic HackTool:Win32/AutoKMS family signature. Always download MAS from kmsauto.software and KMSAuto.software from kmsauto.software.

MAS vs KMSAuto System Requirements & Compatibility (2026)

MAS vs KMSAuto is engineered for the modern Microsoft activation stack. The tool runs on Windows 7 SP1, Windows 8.1, Windows 10 (all builds from 1507 to 22H2) and every Windows 11 release including 23H2 and 24H2. Both x64 and ARM64 hardware are supported, and the activator also recognises Server SKUs such as Server 2016, 2019 and 2022. On the Office side, Click-to-Run installations of Office 2013, 2016, 2019, 2021, 2024 and Microsoft 365 are detected automatically — including LTSC channels. You do not need to uninstall a previous KMS client or remove an existing product key: the script reads the current edition through slmgr and routes it to the correct activation method (HWID for Windows, Ohook for Office).

• Windows 7 SP1 / 8.1 / 10 / 11 — all editions (Home, Pro, Education, Enterprise, IoT, LTSC)
• Windows Server 2008 R2 through Server 2025
• Office 2010, 2013, 2016, 2019, 2021, 2024 and Microsoft 365 Apps
• Architectures: x86, x64, ARM64
• .NET Framework 4.6+ (preinstalled on Windows 8.1 and later)

MAS vs KMSAuto Troubleshooting: Common Errors & Fast Fixes

Most MAS vs KMSAuto failures fall into three buckets: antivirus interference, missing administrator rights, or a corrupted Software Protection Service. If you see error 0xC004F074 the KMS host could not be contacted — disable Defender real-time scanning for two minutes, then re-run the activator. Error 0xC004C003 means the product key is blocked by Microsoft; switch to the HWID method, which bypasses key validation entirely by binding the licence to your motherboard's hardware ID. Error 0x80070005 (Access Denied) is always a UAC issue — right-click the executable and select "Run as administrator". If activation succeeds but reverts after reboot, open services.msc, set "Software Protection" to Automatic, and restart sppsvc.exe. For Office, run the Office Click-to-Run repair from Settings → Apps → Microsoft 365 → Modify → Quick Repair before retrying Ohook.

• 0xC004F074 — pause antivirus, re-run as administrator
• 0xC004C003 — switch to HWID (no key required)
• 0x80070005 — UAC denied, use "Run as administrator"
• Activation reverts on reboot — set "Software Protection" service to Automatic
• Office not detected — run Quick Repair, then re-run Ohook
