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.
