Windows 10: Account Sign-In Hidden from Sign-in Menu/Start Menu

My younger brother and I share a computer. It is Windows 10 Pro. I was letting him use it while i was asleep. All I know is that he was playing his video games. Anyways, he left the house to go hang out somewhere and i wake up to see that when i turn on the computer, only his account shows at the sign-in screen. Meanwhile, there are THREE accounts on this computer. My account, His account, and a local that my other siblings use sometimes. I restarted and even shut down my computer about 4 times. I waited until he came back and logged on his account to check what was wrong, and I see that my account is still there with all my files and docs. The other local account is there too. I log out to see if my User name is there but it isn't. I tried to see if my account was deactivated using these methods but none of them worked. I've looked on Microsoft's forums but all I found was how to activate the built-in administrator account. Please do your best to help!! I have important work to do on my account but i can't access it.

Cortana's What Can I Help You With?

I'm afraid I don't understand the phrase "After signing out your Microsoft account from Cortana."

Do you mean go into Cortana from the start menu and sign out? I have never signed in. When I select Cortana from the start menu, it it invites me to sign in.

The Taskbar Tidbits is already toggled to disable the feature, in Settings.

 

User Accounts

Hi

I have 2 user accounts on my laptop, mine and my wife's. When I am signed into my own account I can switch to my wife's account by just signing into hers from the start menu. No problem with that. But when I sign out of my wife's account, on the display
screen that appears, I don't get an option to sign into my account. When I click on the picture it keeps going back to my wife's login screen. The only way I can get back into my own account is not to sign out of my wife's account but simply to sign in directly
from the start menu into my account, "switching users". Is this a software problem?

Thanks
