Amazon.com just posted my five star review of Windows System Programming, 4th Ed by Johnson M. Hart. Addison-Wesley provided a free review copy. From the review:
I read Windows System Programming, 4th Ed (WSP4E) by Johnson M. Hart after finishing Windows via C/C++, 5th Ed (WVCP5E) by Richter and Nasarre. While I liked WVCP5E, I found WSP4E to be the better book for the sort of understanding I was trying to achieve. I'm not a professional Windows programmer, but I wanted to learn more about how Windows works. Hart's book did the trick, especially for a person like me with more of a Unix background. If you want to better know how to program on Windows, and specifically recognize differences among using the C libraries, the Windows API, and Windows "convenience functions," WSP4E is the book for you too.
