I have an HP laptop that came pre-installed with windows 10. MSFT update asked me to update to windows 11. Now I can't activate it. I tried using the original product key and it's is rejected. How can I fix this or get support from someone at MSFT?

I reinstalled from scratch making a boot usb drive and using this hack to allow me to go to previous version of install, so I could ensure Windows 11 Home was selected. https://www.youtube.com/watch?v=fYoQ_pPs_MQ&t=144s. After the install it was automatically activated (likely found the digitial key).

Unfortunate that windows update led me astray.

    Hi,

    My name is Igor. It's a pleasure for me to help others and I'll try to help you. I am merely a fellow user trying to provide insight and information that may be helpful to others.

    What exactly did you receive as a confirmation Windows 10 retail version? Please show Activation page of Settings and the result of slmgr /dlv command.

    Note, this is strange purchase, because laptop with retail Windows is noticeably more expensive than laptop with preinstalled Windows. I may suppose that unfair seller took a laptop without Windows and installed illegal system.

    Please run Windows Terminal and run

    powershell "(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey"

    command. If it will show product key (do not type it here), reinstall Windows 11 Home.

    If you're unable to activate Windows 11 after upgrading from Windows 10, there are a few steps you can take to troubleshoot the issue:

    1. Check Compatibility: Ensure that your HP laptop meets the system requirements for Windows 11, including TPM 2.0 and Secure Boot.
    2. Use the Correct Product Key: Make sure that the product key you are using is for the correct edition of Windows 11. If your original product key is not working, it may be because it is tied to Windows 10 Home and you are trying to activate Windows 11 Pro, for example.
    3. Firmware-Embedded Activation Key: If your device has a firmware-embedded activation key, it should automatically activate Windows 11. You can check for this key by running the following command in an elevated PowerShell prompt: 
         (Get-CimInstance -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey
    4. Contact Microsoft Support: If the above steps do not resolve the issue, you may need to contact Microsoft support for assistance with activation. You can reach out through the official Microsoft support channels.
    5. Reinstall Windows 10: As a last resort, you can consider reinstalling Windows 10 and then attempting the upgrade to Windows 11 again, ensuring that you follow the proper upgrade paths.

    By following these steps, you should be able to resolve your activation issues after the upgrade to Windows 11.
