Exposes methods that set notification information and then display that notification to the user in a balloon that appears in conjunction with the notification area of the taskbar.
Note IUserNotification2 differs from IUserNotification only in its Show method, which adds an additional parameter for a callback interface to communicate with the notification. Otherwise the two interfaces are identical in form and function. CLSID_UserNotification implements both versions of Show as an overload.
