Hi, I really need some help, and soon
I was trying to get my speaker system to work, and I flipped the switch on the power strip that my computer is plugged into. The computer shut down, and when I turned it back on, the login screen was different. It was the normal blue one before, with the users displayed so you can click on one and enter your password, but now it is a box, and you have to type in the username AND password!!! Someone help me, My mom is gonna be soooo mad at me...

I don't know why this would have changed by rebooting the computer but I think you need to google "fast user switching" and you will see how to change this setting. Let us know if you get it fixed.
