Windows 7 Movie Maker
If you have just upgraded to Windows 7, you will discover that quite a few applications that were present in previous Windows versions are missing, and Windows Movie Maker is one of them. However, if you want to get the Movie Maker on your Windows 7 running machine all you have to do is follow a few easy steps.
Click the Start button and type: essentials and then click the Go to Windows Live Essentials link.

This will take you to the http://download.live.com/ where you should scroll down to the bottom of the page and click the link next to “upgrading to Windows 7.” The programs that you can download are:
* Messenger
* Mail
* Writer
* Photo Gallery
* Movie Maker
* Family Safety
* Toolbar
* Microsoft Office Outlook® Connector
* Office Live Add-in
* Microsoft Silverlight
Click the download button and save the installation file on your hard drive. Once you run it, you can choose which applications you want to install. If Windows Movie Maker is the only one that you need, then deselect all the others and finish the installation.
The Windows Live Movie Maker is slightly different from the previous versions and it seems that it has been created with the novice user in mind – it is extremely easy to use and you can create a movie from your pictures and videos in a matter of minutes, but if you need a serious editing program, you might have to look for other alternatives.
