How to Use KMSAuto 정품인증 방법 2026 — 완전한 가이드

Overview

How to use KMSAuto, written for someone who has never touched Windows licensing before — every step, every prompt you will see, and the command that proves it worked. This guide covers what the tool actually does under the hood, the exact steps from download to verified activation, which engine matches your edition, and how to confirm the result with Microsoft's own slmgr commands. Free, portable, offline-capable, no installer, no password, no telemetry, no ads.

What KMS Auto actually does

KMS Auto is a front-end for licensing machinery Microsoft already ships. Understanding that removes most of the fear around it: nothing is patched, nothing is injected, and every action has a manual command-line equivalent.

• Reads your current licensing state through the Software Licensing Service (slmgr /dlv)
• Installs the correct GVLK (generic volume license key) for your detected edition
• Points the licensing service at a reachable KMS host, or requests an HWID digital license directly from Microsoft
• For Office, applies the Ohook shim so the Click-to-Run licensing check resolves locally and offline
• Leaves no service, no scheduled task and no driver behind when you delete the folder

Step-by-step: download to activated

Five steps, usually under three minutes from download to a permanently licensed machine.

• Download the ZIP from officialkmsauto.com and check the published SHA-256 before extracting
• Add the extract folder (for example C:\Tools\KMSAuto) to Windows Security → Virus & threat protection → Exclusions
• Right-click KMSAuto.exe → Run as administrator (the UAC prompt is expected)
• Pick the engine that matches your product: HWID for Windows 10/11, Ohook for Office, TSforge for Server / LTSC / ARM64, Online-KMS for 180-day renewable
• Wait for the green 'Activation successful' banner, reboot once, then verify with slmgr /xpr in an elevated Command Prompt

Which engine matches your product

Picking the right engine is the single biggest factor in whether activation is permanent or a renewable lease.

• HWID (digital license) — permanent for Windows 10 / 11 Home, Pro, Education, Pro for Workstations and ARM64
• KMS38 — permanent until January 2038 for LTSC, IoT, Server and Education where HWID is unavailable
• Online-KMS — 180-day renewable lease for any volume edition, no local KMS server required
• Ohook — permanent for Office 2024 / 2021 / 2019 / 2016 and Microsoft 365 Apps for Enterprise, fully offline
• TSforge — newest engine for Windows Server 2025 / 2022 / 2019 / 2016 and CSVLK scenarios

Verify the result yourself

Never trust the tool's own banner alone. Windows ships four commands that report the truth about your license state.

• slmgr /xpr — reports whether the machine is permanently activated
• slmgr /dlv — full licensing detail including the activation ID and KMS lease
• slmgr /dli — short license summary and partial product key
• ospp.vbs /dstatus (in the Office install folder) — Office license status

Supported products in 2026

The 2026 release covers every modern Microsoft product still in mainstream support.

• Windows 11 24H2 / 25H2 — Home, Pro, Enterprise, Education, LTSC, IoT, ARM64
• Windows 10 22H2 plus LTSC 2021 / 2019 / 2016
• Windows Server 2025 / 2022 / 2019 / 2016
• Office 2024 / 2021 / 2019 / 2016 (LTSC and Retail)
• Microsoft 365 Apps for Enterprise via the Ohook patch
• Project and Visio 2024 / 2021 / 2019

When it fails, and why

Roughly 90% of failures trace back to three causes. Defender quarantines the executable mid-run (fix: add the extract folder to Exclusions before launching). The licensing cache is stale (fix: slmgr /upk, then slmgr /rilc, then slmgr /ato). Or the engine does not match the edition — HWID cannot license an LTSC build, and Online-KMS cannot produce a permanent Windows 11 Pro license. For 0xC004F074, 0xC004C003, 0xC004F050 and 0x80070005 see our error-code index.

Legality and the honest caveat

Volume-licensing tools are intended for machines you already own a license for, or for evaluation and lab environments. If you are activating a work device, buy a retail or volume license — that is the only route with support entitlement and audit compliance. This guide documents how the mechanism works; the licensing decision is yours.

How to Use KMSAuto System Requirements & Compatibility (2026)

How to Use 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)

How to Use KMSAuto Troubleshooting: Common Errors & Fast Fixes

Most How to Use 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
