Up until a week or so ago, when Windows 8.1 started up it would go to lock screen and then I would click the screen to get to the login page. There I would click my account and get to my desktop. I don't know what settings I changed but now I don't see the lock screen on startup and I get logged in automatically. I went to netplwiz and the box next to "User must enter a username and password to use this computer" is already checked. I would like to revert back to the way it used to startup but I can't find how to do it.
