Windows Update

Upgrade Windows 11 Home to Windows 11 Pro

by Joaquinne Dela Cruz 14 Jul 2026

Before You Begin

To apply a Windows Pro license to a device where you have installed Windows Home, Windows must first be switched to the Pro edition using Microsoft’s generic Pro upgrade key. This key changes the edition of Windows but does not activate it.

Ensure that your Windows is compatible for an Upgrade

1. Press on your keyboard WinKey + R / search "Run" on your search bar

2. type "winver"
This will show a popup and confirm windows version is "Version 22H4 / HIGHER"

________________________________________________________________________________________________

Upgrade Process

1. Disconnect from the Internet

Before starting the upgrade process, disconnect the device from the internet.

2. Enter Audit Mode

At the Windows Out of Box Experience (OOBE) screen ("Let's start with region"), press:

CTRL + SHIFT + F3

The device will reboot and automatically enter Audit Mode.

3. Open Activation Settings

Navigate to:

Settings → System → Activation

4. Change the Product Key

Select Change Product Key and enter the generic Windows Pro upgrade key:

VK7JG-NPHTM-C97JM-9MPGT-3V66T

This key is provided by Microsoft for edition upgrades and does not activate Windows.

5. Allow Windows to Upgrade

Windows will begin converting from Home to Pro. This process may take several minutes, and the device may restart.

6. Run MAJOOL

Once the upgrade has completed and Windows Pro is installed, launch the MAJOOL Client and inject a valid Windows Pro license.

Troubleshooting

Black Screen After Upgrade

In some cases, Windows may display a black screen with a visible mouse cursor after the edition upgrade.

If this occurs:

  • Hold the power button to shut down the device.
  • Power the device back on.
  • Allow Windows to complete any pending configuration tasks.

Upgrade Fails

If Windows does not accept the generic upgrade key:

  • Confirm the device is currently running Windows Home.
  • Ensure the device is disconnected from the internet.
  • Restart the device and try again.
