Minimize the Foobar2000 media player to the system tray if you don't want to display its icon on the taskbar in Windows 8's Desktop view. Foobar doesn't minimize into the system tray by default when you click the "Minimize" button; you must enable this option from the Preferences window. You can control the playback of your media files directly from the system tray after you minimize the program and even access the Preferences window without maximizing the Foobar software.
Enable the Minimize to Notification Area Option
Launch the Foobar2000 program and then open the Preferences window by clicking "File" and then "Preferences." Alternatively, open the Preferences window using the "Ctrl-P" keyboard shortcut.
Double-click the "Display" node in the left pane to expand it and then select the "Default User Interface" item to display all settings related to the user interface.
Locate the "Minimize to notification area" option in the System Notification Area section and enable it. Ensure the "Always show notification area icon" option is also enabled -- otherwise you can't control the media player from the system tray.
Click the "Apply" button to apply the new settings and then click "OK" to close the Preferences window. You don't need to restart Foobar; the settings are applied immediately. To test them, click the "Minimize" button in the upper right corner of the Foobar2000 window; the program minimizes and its icon appears in the system tray.
