There have been solutions for this in Windows Movie Maker 6.0 previously but it required customization of the XML. It also didn't have an ability to fade the logo in and out. I've decided to create an installer that makes it much easier, doesn't require editing of the XML and also adds a fading version.
There are two installers depending on whether you are running on a 32-bit or 64-bit version of Windows. The installer will put the necessary files into, C:\Program Files\Movie Maker\Shared.
