23. Desktop slideshow

Windows 7 comes with some very attractive new wallpapers, and it's not always easy to decide which one you like the best. So why not let choose a few, and let Windows display them all in a desktop slideshow? Right-click an empty part of the desktop, select Personalise > Desktop Background, then hold down Ctrl as you click on the images you like. Choose how often you'd like the images to be changed (anything from daily to once every 10 seconds), select Shuffle if you'd like the backgrounds to appear in a random order, then click Save Changes and enjoy the show.
