If you're wondering why there isn't a search box on your start bar yet, that's because you have to activate it.
Find a blank spot on your start bar that contains no icons, buttons or anything else. Right Click it, you will get a menu up. One of the options is "Toolbars". Choosing that will give a sub-menu, one option of which is "Chris's Desktop Google" - select it.
You're up and running. Type a query in to the box and press return to check everything's running okay.
