Right-click on the Windows desktop, choose Properties, click Desktop, and
either choose "None" or find an image you like. Note that you can have an
image centered on the screen, tiled (i.e. repeated across the screen) or
stretched to your screen's dimensions. Experiemnt as well with the other
settings you can change, and for additional assistance, do Start > Help and
Support, and search on the area you need assistance with. There is a
powerful computer manual built right into your operating system. And it's
free.
