ITaskbarList2  Interface

IID_ITaskbarList2

{602D4995-B13A-429B-A66E-1935E44F4317}

The ITaskbarList2 interface extends the ITaskbarList interface by providing a method to mark a window as a full-screen display.

Remarks

The Shell also automatically attempts to detect full-screen applications, but it is not as reliable as using the ITaskbarList2::MarkFullscreenWindow method.
