How to Use Windows DreamScene to Set Video as Motion Desktop Background

Once you install Windows DreamScene, just right-click on Windows Vista desktop and then select “Personalize”. In the Personalization window, select “Desktop Background”. And at the Picture Location drop-down list, select “Videos” or “Windows DreamScene Content”. You will be shown a list of video available. Simply pick a video and here you go to enjoy the motion desktop video background experience.

This release has been tested as working on Windows Vista Ultimate RTM activated. It is unlikely to work on unactivated Windows Vista systems or any other flavors of Vista or non-Vista system.
