How to reactivate my original Windows 11 Home version after a big hardware repair

How does one reactivate an original Windows home version after a hardware repair, please. The shop changed my PC motherboard and installed Windows Pro instead (which has now expired of course). The laptop in question was purchased in 2022 so was Windows 11. The error message says I need to talk to an admin but I don't have one... (Do they mean the repairs shop?). All tips gratefully received! Thanks!

    1

    Where did you get your Windows licence was that pre-installed on the laptop or did you purchase a full retail Windows licence direct from Microsoft or from a 3rd party retailer, and if so, do you have the product key?

    2

    Click your Start Button, type cmd then right click Command Prompt and choose 'Run as Administrator'

    Run or paste this command and hit Enter:

    slmgr.vbs /dlv

    Please post a screenshot of the resulting dialog

    To reactivate your original Windows 11 Home version after a hardware repair, you can follow these steps:

    1. Use the Activation Troubleshooter: Go to Settings > Update & Security > Activation. If Windows is not activated, you should see an option to troubleshoot. This can help you reactivate Windows if the hardware changes are detected.
    2. Sign in with your Microsoft Account: Ensure you are signed in with the same Microsoft account that was used to purchase or activate Windows 11 Home originally. This can sometimes help in reassigning the license to your new hardware.
    3. Contact Microsoft Support: If the troubleshooter does not resolve the issue, you may need to contact Microsoft Support for assistance. They can help you reactivate your license based on your account history.
    4. Check for a Digital License: If you have a digital license associated with your Microsoft account, it should automatically reactivate when you connect to the internet. If it doesn't, you may need to provide proof of purchase to Microsoft Support.
    5. Reinstall Windows 11 Home: If all else fails, you may consider reinstalling Windows 11 Home using a bootable USB drive. Ensure you have your original product key if required during the installation.

    If the error message suggests contacting an admin, it likely refers to the support team at the repair shop or Microsoft Support if the issue persists after trying the above steps.
