Activate Windows Without Product Key Using CMD — 3 Commands

Activate Windows 10 or 11 using only Command Prompt — no GUI tool, no product key purchase. Three slmgr commands and you're done in under 60 seconds.

This is the manual (no-GUI) method for KMS activation. It uses Windows's built-in slmgr.vbs script — the same tool Microsoft enterprises use to activate volume licenses.

Step 1 — Open Command Prompt as Administrator

Press Win + X → Windows Terminal (Admin) or search cmd → right-click → Run as administrator.

Step 2 — Run These 3 Commands

Replace the key with the correct GVLK for your edition — see the full GVLK list.

Activating Windows from Command Prompt, no key required

Windows ships with a built-in licensing tool, slmgr.vbs, that can activate the system using the public Generic Volume Licence Keys — so you never type a purchased product key. The trick is that these GVLKs are designed to activate against a KMS host, which is the one piece a home PC lacks. You can either point at a host manually, or let KMSPico provide one locally.

The command sequence

From an elevated Command Prompt (right-click → Run as administrator):

slmgr /ipk <edition GVLK> — install the generic key for your edition
slmgr /skms kms-host — point at a Key Management Service host
slmgr /ato — activate
slmgr /xpr — confirm the activation status

The full key list and explanations are in our slmgr command reference.

The easier alternative

If you'd rather not run commands, KMSPico performs this exact sequence automatically and hosts the KMS service for you. For an entirely offline version of this method, see activate without internet.
