KMSAuto vs HWID vs MAS — Porównanie 2026

Overview

KMSAuto vs HWID vs MAS in 2026 — Which Activator Wins — the newest 2026 method confirmed working after Microsoft's latest licensing-server tightening. This guide covers the exact steps, which engine matches your scenario (HWID for Windows, Ohook for Office, TSforge for Server / LTSC / ARM64), and the fix for every common error code. Free, portable, offline, no installer, no telemetry, no ads.

Step-by-step instructions

Five steps, under three minutes from download to permanently activated.

• Open Windows Security → Virus & threat protection → Manage settings → Add C:\Tools to Exclusions
• Download the 2026 build, verify the SHA-256 checksum shown on the download page, extract the ZIP to C:\Tools\KMSAuto
• Right-click KMSAuto.exe and choose Run as administrator (UAC prompt is expected and safe)
• Match the engine to your product — HWID for Windows permanent, Ohook for Office permanent, TSforge for Server / LTSC / ARM64, KMS for 180-day renewable
• Wait for the green 'Activation successful' banner, then reboot once — the license is now bound to your hardware ID and survives reinstall

Which engine to pick

Match the engine to the exact product and edition for the cleanest result and the longest license.

• HWID (digital license) — permanent for Windows 10 / 11 Home, Pro, Education, Pro for Workstations, ARM64
• KMS38 — permanent (until 2038) for Windows 10 / 11 LTSC, IoT, Server, Education when HWID is unavailable
• Online-KMS — 180-day renewable KMS for any volume edition without a local KMS server
• Ohook — permanent for Office 2024 / 2021 / 2019 / 2016 LTSC and Microsoft 365 Apps for Enterprise
• TSforge — newest engine for Windows Server 2025 / 2022 / 2019 / 2016 and CSVLK scenarios

Why pick this build

Portable — extract, run, delete. Every release is signed by the original author and mirrored from the official source.

Troubleshooting common errors

Roughly 90% of activation failures come from three causes: Defender quarantining the EXE mid-run, a stale KMS licensing cache (fix: slmgr /upk, slmgr /rilc, slmgr /ato), or the wrong engine for the edition. Extract to a Defender exclusion folder (C:\Tools\KMSAuto), run elevated, and match the engine to the product. For 0xC004F074, 0xC004C003, 0x80070005 and 0xC004F050 see our error-code index.

KMSAuto vs HWID vs MAS System Requirements & Compatibility (2026)

KMSAuto vs HWID vs MAS 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)

KMSAuto vs HWID vs MAS Troubleshooting: Common Errors & Fast Fixes

Most KMSAuto vs HWID vs MAS 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
