I can't get past the sign in screen on windows 10

[WPCentral Question]

I have installed windows 10 and it was working last night. Turned on today and a blue sign in screen with a circular person icon, PC and sign in to the left of the windows logo. Wireless icon, another icon, and a start button in the bottom right hand corner. Can get a view from a cave to sea with date, digital clock plus battery and wireless icon bottom right hand corner from the top of the screen but if I click on it it vanishes. Tried clicking on all icons and nothing happens. I am no techy so need some help please.

Click on the center of the lock screen, press enter, or swipe up. These are the three ways to get to sign-in.
