Microsoft Windows Movie Maker (available with Windows XP and Vista) is a very simple to use video editing application for creating small movies at home.
Here is a free tool called Windows Movie Maker Installer that allows you to install Microsoft Windows Movie Maker 6.0 in a fresh installation of Windows 7.
The specialty about this tool is that you can enjoy DV export and a true timeline that are not found in the new Windows Live Movie Maker.
Both versions of Movie Maker may be installed side-by-side though if needed. This installer supports both 32-bit and 64-bit platforms.
