I found out that windows 7 does not come with all of the programs you would expect. I wanted to post a video to my Facebook account, but it needed a little editing. It just needed to be trimmed a little, should not be a problem for Movie Maker. I look in the start menu, and it is not there. After a short web search, I find that it is only available as a download from live.com.
So I install the Movie Maker beta, anticipating an improved program. I am actually shocked when I first open MM, it does not look like an editing program. It takes a bit, but I figure out how to trim/crop my video . The controls are so imprecise, that I could not get the trim points right. They were about 20 seconds from the spot I needed. I was able to get my video posted, but this is the last time using MM.
