Windows 10: Problems with my MS account

Windows does not allow me to log in with my MS account. I get an error message locally on my computer that the login attempt failed screenshot attached. I can neither log on to Windows nor to Outlook.

How can I solve the problem?

Login not accepted for my MS Account

Let me explain, again, what I have experienced:

• I use my MS account to unlock this computer. No problem doing that
• I attempted to use other apps requiring the MS login, like Outlook, or even this forum, and it would not accept the very same credentials I used to unlock the computer
• I used my wife's MS account to login to this forum so that I could seek help
• I have tried resetting my MS account twice, and that did not work either.

I would appreciate suggestions OTHER than wha I have already tried

 

Remove account

I suggest you backup your personalized files first before removing the account.
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:
