Windows Side Bar

The Windows Sidebar is a widget engine for Desktop Gadgets that is anchored to the side of the Windows Vista desktop. Users can add gadgets from gallery.live.com which were made by other users. Sidebar gadgets can perform various tasks, such as displaying the time and date and showing the CPU usage.

The Sidebar contains mini-applications or Gadgets which may be used to display information such as the system time, Internet-powered features such as RSS feeds, and to control external applications such as Windows Media Player. Desktop Gadgets can also run on the Windows desktop, separate from the Sidebar.

Compatible with both SP2 and SP3 for Windows XP!!!
