Windows security keeps asking me to sign in, but the wrong username appears. I press more choices to sign in with the correct account, but it continues to bring me to the wrong username. How do I get rid of the wrong account?

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:

 

Sign in with a Microsoft account instead. Administrator account

I have Windows 10 Pro since its release. Today, I decided to switch the email account for the computer administrator account. The following steps outline the sequence of events;

1. I logged in as a local account.
2. Clicked on Sign in with a Microsoft account instead
3. Followed the steps prompted. I entered my email of choice and the corrected password, then verified through the authenticator app.
4. I was asked to enter the password again, and now I am getting an error message that the password is incorrect
   but the password is correct 100%
5. Researched possible solutions
   • Used the English (United States) keyboard
   • Used on-screen keyboard
   • Reverting to Windows 7 is not possible as I never had it on my laptop
   • Reset my password
     • Nth worked

Please help me sign to my email account on this computer as an administrator
