Windows Movie maker which used to be a part of Win XP, is not included in Win 7 and must be downloaded from Microsoft - this is what I had to do with my Win 7 OS. Movie Maker is a nice program and I have used it. Since we are on the subject, also consider ULead DVD Movie Factory.
What I found installed was Movie Maker Live... what a piece of.... (pardon me).
Luckily I downloaded the 2.6 version that came with Vista and I was back in business.
I cannot believe the "geniouses" at Microsoft convinced themselves to make Movie Maker a poor piece of software in comparison to what it was before.
Thank you for your suggestion.
