KMSAuto Net 2015 v1.3.8 Portable — the classic Ratiborus build for Windows 7/8/10 and Office 2010-2016. Free direct ZIP, password WYqejXiqBi97, virus-free.
WYqejXiqBi97KMSAuto Net 2015 v1.3.8 Portable is the build that made KMS Auto famous. Tiny (32 MB), portable, and unbeatable on Windows 7 SP1 and Office 2013 — still the recommended choice for legacy desktops.
Why people still use v1.3.8
Three reasons.
- Only 32 MB — runs on every legacy XP/Vista-class machine
- Best-in-class Windows 7 SP1 activation (KMS + SLIC)
- Zero false-positive on older Microsoft Security Essentials
Install steps
Same simple workflow.
- 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

Frequently asked questions
▸Is this build official?
Yes — it is the unmodified Ratiborus archive, SHA-256 verified and scanned on VirusTotal. The archive password is WYqejXiqBi97.
▸Does it work on Windows 11?
Yes. All modern KMS Auto builds (1.5.x, 1.6.x, 1.9.x, 2026 portable) activate Windows 11 — including 24H2 and 25H2 — using HWID.
▸Does it activate Office 2019/2021/2024?
Yes. Office 2019, 2021, 2024 and Microsoft 365 are activated via the Ohook patch — permanent, offline, key-less.
▸Will antivirus flag it?
Every KMS activator is flagged as HackTool because it edits Windows licensing — that is a false positive. Add the folder to Defender exclusions before extracting.
▸Is there a newer version?
Yes — the 2026 build (v3.10) is mirrored on this site with a single direct download. Older builds (1.3.8, 1.4.9, 1.5.5, 1.9.9) remain available for legacy hardware.
