Question: How can I permanently hide (not disable) the “Wireless No Connection” Icon in System Tray? I can make a registry entry to disable the both wire and wireless icons permanantely ( HKEY_CLASSES_ROOT\CLSID\{7007ACCF-3202-11D1-AAD2-00805FC1270E} ). However, the wireless icon is useful when connecting to a wireless network and I would like it to behave like the Wired icon by conforming to the settings in the Customize Notifications dialog and the Wireless properties dialog.
