In any Windows-based PC, you can change the background color or add a photograph to your desktop (Windows calls this "wallpaper"). All you have to do is find a picture you like, click on it, and a larger image will appear. Right-click on that image, then select "Set as Wallpaper" and you'll have a 800x600 copy on your desktop. Here are a selection of wallpaper images you can use to brighten your computer screen.
