Windows 10: Can't register my Win 10 desktop with my MS Account

The instructions:

Windows 10 PCs
Add your PC to use Find My Device and get support for it

To add a Windows 10 PC:

1. Go to Settings > Accounts > Your info

2. Select Sign in with a Microsoft account instead

If your PC still isn't showing up, try adding the Microsoft account again.


No option for Sign in with a Microsoft account instead



Further, my desktop was listed twice but it could not be found.

I have changed motherboards twice, so figured I should remove those two invalid listings and register it newly, but no....


What to do?

:)

To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:
   
   Code:

   net user test /del

 

Can't sign in with MS account in Win 10

Thanks, this was not my fault or mistake. I just switched to local account from MS account. It's very simple to back again to MS account. It's a fault of MS insider build. Afterall I tried as per your suggestions. My existing MS account is not removing from
the list. Taskbar start menu not working. Very bad situation. I can't get further updates.

Any other help plz.
