locate the logon screen picture and set it as default or choose another picture.

or you can download microsoft theme from http://windows.microsoft.com/en-US/windows/themes and use any picture you like as your logon screen.

alternatively, you can open microsoft paint, then save a blank.jpg or blank.png and set either one as logon screen. (blank white space)
