Good question, and good guess too. I did use Windows Movie Maker, I imagine you could tell because of the titling and the effects used on the black and white bit.

This video is part of a course on using Windows Movie Maker, as well as on video editing and movie making in general, so I guess I had to use WMM.

I do like Windows Movie Maker because its so straight-forward, but prefer to use Adobe Premiere, you can do so much more with it.
