Remarks

This API allows you to examine the hosting behavior of a window after it has been created. A window's hosting behavior is the hosting behavior of the thread in which the window was created, as set by a call to SetThreadDpiHostingBehavior. This is a permanent value and cannot be changed after the window is created, even if the thread's hosting behavior is changed.
