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.

    The installation should use a key in BIOS and install correct edition automatically.

    Meanwhile please repair system files by

    DISM.exe /Online /Cleanup-Image /RestoreHealth

    command from Windows Terminal (admin) environment and re-run commands to see a key.

    Seems something is wrong with the system.

    Please contact HP support and ask whether Windows was preinstalled to this laptop.

    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.

    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.
