Now that you have all the elements from Title through Credits in the correct order on your Windows Movie Maker timeline, you can play the entire video to do a final preview prior to publishing. Make any last minute adds, deletions, or tweaks to adjust the overall flow of your slideshow movie then click Publish to your PC / computer.

Give the movie a nice, keyword-rich filename (which YouTube will index later) and click publish / finish. The movie production / conversion process can take several minutes, depending on the length of the audio and number of pictures involved.
