fade The End title to black leaving that black clip up for 10 seconds

ta - dah ... you made a video!

This is what Windows Movie Maker looks like when it's first launched

If this is your first time looking at it, remember (this goes for all editing systems) --- don't let all the new words, terms etc overwhelm you. Almost all video systems and equipment say what they want you to do right on the buttons. Don't try to absorb the entire window, break it down into small sections. 

The upper left open area with Video Effects and Transitions is the tools and clip area. Your clips start there along with the tools that you can use with the clips. 

The next white window is where the clips for a particular project will live.

To the right of that is the viewing monitor. More complicated editing systems have 2 monitors, one for your footage and one for the project itself. 2 monitors make it easier.

The bottom half is the Timeline or Sequence.  Right now it's showing in the storyboard. That is very confusing even for me, a longtime editor so please switch it to "Show Timeline", by clicking that icon,

so that your screen changes to the image below.
