Just right-click on a blank area of the desktop and click Properties. The setting is under the Desktop tab. Hope this helps...Why am I unable to change my desktop wallpaper? I know how to do so, The option isn%26039;t there.?
Instead of using the control panel why don't you just right click anywhere on the desktop and choose properties - In the Desktop TAB you can either choose your wallpaper or browse your computer for more options.
If the option is greyed out then most likely there is a video / display problem with your computer.
