Common Windows taskbar problems include a missing taskbar, incorrect sizing of the taskbar, and the taskbar displaying on the top, right or left side of the computer screen. Sometimes the taskbar displays too many rows of icons, and some users have difficulty adding or removing icons from the taskbar.
The Windows taskbar can become inaccessible when auto-hide is activated. To turn off auto-hide in Windows XP and earlier versions, bring up the Start Menu using the Windows keyboard key or press ESC and CTRL simultaneously. Deselect the Auto-Hide option. In Windows Vista or later, access the Control Panel using the same steps. From there, select Taskbar and Start Menu, then uncheck Auto-hide the taskbar.
