I recommend performing a repair installation via Settings or using the Windows 11 ISO.

Open Settings > System > Recovery.

Few things to check on the PC

  • Unplug all external peripherals except for the Mouse, Keyboard, and LAN cable before starting
  • Disable or uninstall any third-party Antivirus program to prevent it from interfering with the upgrade

Under Fix problems using Windows Update, click Reinstall Now

Once completed, your system will restart.

Alternatively, you can use the Windows 11 ISO by following the steps in the link below.

After that, perform the steps again in my first reply and let me know how it goes.

    Hello,

    Since you already paid the Pro upgrade fees, it is assumed you’ve successfully bought Pro upgrade.

    In this case, you can simply change your edition to Pro using generic product key.

    If issue still persists, refer this fix:

    The error code 0xc004f050 typically indicates that the Software Licensing Service reports that the product key is invalid. This issue can occur for a couple of reasons:

    1. The licensing monthly rollup/security only/standalone package isn't installed on your computer.
    2. You may have installed the prerequisite updates but did not restart your computer.

    To resolve this issue, you can try the following steps:

    1. Check your update history to ensure that all necessary updates for the upgrade have been installed successfully.
    2. Verify that the product key you are using is correct for your version of Windows 11 Home and that it matches the upgrade to Pro.
    3. Restart your computer and try the upgrade process again.

    If the problem persists, you may need to contact Microsoft Support for further assistance.
