If you mean the menu when you click on "Start" then you can drag and drop anything to the list on the left hand side. and you can remove anything by right-clicking that item and select remove from this list. If you want to add or remove stuff on the right hand side you can do so by right-clicking the start button and select properties, then select "start menu" tab, "customize", "advanced" tab and you can add and remove any of the items in that list. If you want to add something that is not on that list, it is possible but it is probably best left alone as it is definately not simple. probably 8/10 in difficulty maybe a 9/10.
