Welcome Screen Not Appearing When Selected

The welcome screen refuses to show, even though i've selected "use the welcome screen" under user accounts. Instead I get the classic logon screen. Interesting to note, is that when "use the welcome screen" is selected, there is a black background to the logon, but when it's not selected (when classic mode is actually supposed to show), I get the logon with the default blue background. I've tried going into regedit and activated it manually, (used a 1 value), but I still get the classic logon screen.
