KMSAuto Download 2026 無料ダウンロード 2026 — Windows と Office ライセンス認証ツール

What KMSAuto is in 2026

KMSAuto started as a single-purpose KMS emulator front-end by Ratiborus. The current generation is better understood as a launcher around several activation engines: HWID for a permanent digital licence on Windows 10/11, Ohook for permanent Office activation, TSforge for LTSC, IoT and Server editions, and the classic KMS emulator for 180-day renewable activation. Knowing which engine you need matters more than which button you press.

• HWID — permanent Windows 10/11 digital licence tied to your hardware
• Ohook — permanent Office 2013–2024 and Microsoft 365 apps activation
• TSforge — offline engine for LTSC, IoT Enterprise and Windows Server
• Online KMS — 180-day renewable lease, the classic behaviour

System requirements

The tool is small and undemanding, but two requirements are non-negotiable: you must run it elevated, and Windows Security must not quarantine it mid-run. Everything else is flexible.

• Windows 7, 8, 8.1, 10 or 11 (32-bit and 64-bit), plus Server editions for TSforge
• Administrator rights — the licensing service rejects unelevated calls
• A folder exclusion in Windows Security for the extract location
• Internet connection only for the initial HWID handshake; Ohook, TSforge and KMS work offline
• No .NET Framework dependency on Windows 10/11 — the current build is self-contained

Video walkthrough

Prefer watching over reading? This short video shows the same flow end to end — downloading the current build, verifying it, choosing the activation engine and confirming the result with slmgr. The written steps below cover the same ground with the exact commands you can copy.

How to verify the download before running it

This is the step every lookalike site hopes you skip. The publisher posts a SHA-256 hash next to the download link; your job is to confirm the file on your disk produces the same hash. One differing character means the file is not the published build — delete it.

• Open PowerShell or Command Prompt in the download folder
• Run: certutil -hashfile OFFICIALKMSAUTO_AIO.cmd SHA256
• Compare the output with the hash published on the download page
• Never trust an archive that asks for a password — passwords exist to stop antivirus scanning the contents

First run: which engine to pick

For a normal Windows 11 Home or Pro machine, pick HWID and you are done permanently. For Office, pick Ohook. Only reach for TSforge when the edition is LTSC, IoT or Server, and only use Online KMS when you specifically want the renewable 180-day behaviour — for example in a test lab you rebuild often.

• Windows 11/10 Home, Pro, Education → HWID
• Office 2013–2024, Microsoft 365 apps → Ohook
• Windows LTSC, IoT, Server 2022/2025 → TSforge
• Lab VMs you rebuild frequently → Online KMS
• Verify any result with slmgr /xpr — 'permanently activated' is the answer you want

Common first-run problems

Three issues account for nearly every failed first run: the file was quarantined before it started (add the exclusion and re-extract), the tool was not run as administrator (right-click → Run as administrator), or the edition does not match the engine (an LTSC machine will never activate through HWID — use TSforge). Error 0xC004F074 after a KMS attempt means no KMS host answered; switch to a permanent engine instead of hunting for hosts.

Get the current build

The current 2026 build is distributed from officialkmsauto.com as a plain ZIP — no password, no installer, no bundled software, no signup. Verify the published SHA-256 before you extract, add the folder to Windows Security exclusions, then run the executable as administrator. Everything on this page works the same whether you use the tool or type the commands yourself.

KMSAuto Download 2026 System Requirements & Compatibility (2026)

KMSAuto Download 2026 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 Download 2026 Troubleshooting: Common Errors & Fast Fixes

Most KMSAuto Download 2026 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
