Windows 11 Pro Product Key Activation

Activate Windows 11 Pro using CMD — no third-party tools required.

Getting Started

Open Command Prompt as Administrator by following these steps:

1. Press Windows key + R to open the Run dialog.
2. Type cmd.exe in the box.
3. Press Ctrl + Shift + Enter to run it as Administrator.
4. Click Yes when prompted by User Account Control.

You should now see an elevated Command Prompt window.

Step 1 — Clear Existing License Data

Run the following commands one at a time, clicking OK after each prompt:

slmgr.vbs /upk
slmgr.vbs /cpky
slmgr.vbs /ckms

These commands uninstall the current product key, clear it from the registry, and remove any configured KMS server.

Step 2 — Check Edition Upgrade Eligibility

Before proceeding, verify that your current Windows edition supports upgrading to Pro:

DISM /online /Get-TargetEditions

If Professional appears in the list, your device is eligible for a free edition upgrade.

Step 3 — Run the Pro Installer

Copy and paste the following commands into the Command Prompt:

sc config LicenseManager start= auto & net start LicenseManager
sc config wuauserv start= auto & net start wuauserv
changepk.exe /productkey VK7JG-NPHTM-C97JM-9MPGT-3V66T
exit

Windows will begin the upgrade process and display a progress percentage. This may take a few minutes.

If an error appears once it reaches 100%, simply click Exit — this is expected behavior.

Restart your PC. Windows will install the necessary updates and features during reboot.

Once complete, go to Settings → System → About to confirm that Windows 11 Pro is now installed.

Important

You may notice that Windows is not yet activated and that some settings are restricted. The next step addresses that.

Step 4 — Activate Windows 11 Pro

Open an elevated Command Prompt again (repeat the steps from the Getting Started section), then run the following commands one at a time:

slmgr /ipk W269N-WFGWX-YVC9B-4J6C9-T83GX
slmgr /skms kms8.msguides.com
slmgr /ato

Once all three commands complete successfully, Windows 11 Pro will be fully activated.

You can verify this under Settings → System → About.
