Microsoft Account sign-in again

In the settings I have an old email address I need to change the one on administrator (there is a screenshot attached). I want to remove that email address (under Administrator) because I already deleted that email on gmail months ago. I have a new email signed in on microsoft account but that is not working because there is always a new notification from microsoft account to fix that and sign in (there is a circle red x). I have no idea how to fix this I tried signing many times and changing forgotten passwords but they all never worked.

Hello Chito, and welcome to Ten Forums. :)

First, double check to make sure that the new email address is the primary alias for your Microsoft account.

Restart the computer. If the new address doesn't show, then switch to a local account, then switch back to your Microsoft account to toggle it.
