When it comes to creating your own icons, your first port of call might be your image editor. You can choose from icons already present elsewhere on your system, or design your own. If you're unhappy with the icons associated with various parts of your PC, though, you'll be glad to know it's possible to change them. Icons brighten up Windows, but they also serve a more practical purpose in helping you to identify folders from files, and different types of file from each other.
