How can I remove the Windows XP notification area (i.e., system tray) from the task bar?

A. To hide the notification area, perform the following steps:

1. Start a registry editor (e.g., regedit.exe).
2. Navigate to the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer registry subkey to hide the notification area for the current user, or navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer registry subkey to hide the notification area for all users.
3. From the Edit menu, select New, DWORD Value.
4. Enter the name NoTrayItemsDisplay, then press Enter.
5. Double-click the new value, set it to 1, then click OK.
6. Close the registry editor and log off or restart the machine for the change to take effect.
