Windows won’t allow you to rearrange the buttons on your taskbar. If your dependent on having something in a particular location, probably because you’re running it all the time and it’s always on the left side… until it crashes, then Taskbar Shuffle is for you. It allows you to drag and drop buttons on your task bar to any location. It also lets you drag and drop the icons in your system tray in the same way. Better yet, it can hide it’s own icon from the system tray so it’s not taking up any valuable screen space.
