Windows Sidebar (New!) is a pane on the side of the Windows Vista desktop that gives you quick access to mini-applications called gadgets that can connect to Web services, such as news headlines, or integrate with many of your applications, such as viewing your calendar. You can customize Windows Sidebar to suit the way you work—whether you want it always on top or resting below maximized windows. If you are having problems with a gadget, you can stop it from running. If the gadget was installed with Windows Vista, you can restore it.
