    Thank you. So you have full license. That will make the issue slightly less complicated.

    Go to Settings > Accounts > Your info

    Click on Sign in with local user instead. follow the steps and finish the rest.

    (If you don't see the "sign in with a local account instead option, click on "Stop signing into Microsoft apps automatically" first, then relaunch this page. )

    Restart the computer (Do Not skip)

    Go to Settings > Accounts > Your info

    Click on Sign in with Microsoft account instead. follow the steps and finish the rest

    Restart the computer (Do Not skip)

    Then run the troubleshooter again, see if the device shows up this time for you to choose.

    ==========

    If the above still doesn't work, Please type cmd in the search on the taskbar. Don't press enter key yet. Instead, choose "run as administrator" to launch Command Prompt.

    Run this command

    slmgr /rilc
    

    Then restart the computer, and run the troubleshooter again. Let me know if there's any changes.

    What make of computer do you have? I have Dell computers and get BIOS updates for them often. All I do is select the update and click on Install Selected for the update and when it has finished, I can go back to using my computer. I don't have to activate windows.

    Did you update anything else on your computer?

    This is an example image from a Dell BIOS update sent to me. This was from another Dell computer that I own but no longer use.

    DellBIOSUpdate1.0.15 - Copy
