Launch System Preferences from the Applications Folder. Click on the View menu, and choose “Customize.” A checkmark will show up next to each preference pane icon, allowing you to uncheck the ones you don’t need in there. Click on the “Done” button in the upper left, and those icons will disappear.
If you want to find them again, simply choose Customize from the View menu again, and the hidden icons will show up, ready for you to check their boxes and make them visible again.
Want even more customization options? Notice in the View menu that you can choose to organize by Categories (default) or Alphabetically. If you’re a fan of the alphabet, that second option should make you squee with delight.
