PRB: Installed DeskBand Not Displayed in Taskbar Shortcut Menu


The information in this article applies to:

  • Microsoft Win32 Software Development Kit (SDK), on platform(s):
    • the operating system: Microsoft Windows 2000


After you install a desktop band object, the band object should be available to the user in the taskbar shortcut menu under Toolbars. On Windows 2000, the newly installed band object might not be present in the Toolbars menu. Restarting the computer does not correct this problem.


The Windows 2000 shell caches the available desktop band objects and only updates this cache if it senses that an installation application is run or if the cache location in the registry is not present.


The ideal solution is to install your desktop band object from an application that has the name Setup.exe or Install.exe. This prompts the shell to rebuild the desktop band object cache.

If this solution is not feasible in your situation, you need to delete the following registry key:

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs.

This causes the shell to rebuild the desktop band object cache the next time the user views the taskbar shortcut menu.


This behavior is by design.
