If you want to get rid of the Sidebar on a more-or-less permanent basis, open the Windows Sidebar Properties dialog box by right-clicking somewhere on the Sidebar (outside of the gadgets) and then click Properties on its shortcut menu. Then click the Start Sidebar When Windows Starts check box to remove its check mark before you click OK. Doing this prevents Vista from starting up the hidden Sidebar the next time you boot up your computer.
