Well, DDK should never be followed or anywhere near windows.h! And NDK 
is an add-on to the DDK/PSDK, so it's normal that it follows. The point 
is to "Add-on" anything that isn't already provided, so a typical 
sequence would look like:

#include <windows.h>
#include <winsock2.h>
#include <ntsecapi.h>
#include <any other header you want"
#define NTOS_MODE_USER
#include <ntndk/ntndk.h>

This would mean the NDK would have to import windows.h, which I don't 
like, because some apps don't need to use windows.h (think Native Apps). 
I prefer to think of the NDK much more as an add-on, then a master 
header set.

Oh, yes, sure. Thanks.

OT: You'll finally get that proper Parse Routine for registry code soon.
