Get rid of the horrible notifications on the right, potentially get rid of the clock with a third-party program, go to deviantArt to find icons for whatever you've pinned to the taskbar, right click them, then right click the program name (right click windows explorer icon, when the menu comes up right click windows explorer again), customize, change icon...
