This has been discussed before but here is the reason (sort of): The hwnd
at the WM_CREATE create message is not "fully initialized" as a window
handle.  You are in the process of creating a window so this kinda makes
sense.  The createstruct pointed to by lParam contains the proper handle
if I remember correctly.  The hWnd passed back from CreateWindow is
valid and will match the handle seen in subsequent messages to your
WndProc.

Hope this clears up the confusion.
