If you are using the Windows Classic theme in Windows XP, the icons in the notification area on the right side of the taskbar may disappear when you select a High Contrast scheme in the Color Schemes box on the Appearance tab.
To work around this problem, right-click a blank area of the taskbar, and then click Lock the Taskbar. Or, change the size of the taskbar, and then restore it.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
