For the first time, the book has been divided in two parts. This was done to get the information out more quickly since it takes considerable time to update the book for each release of Windows.
Part 1 begins with two chapters that define key concepts, introduce the tools used in the book, and describe the overall system architecture and components. The next two chapters present key underlying system and management mechanisms. Part 1 wraps up by covering three core components of the operating system: processes, threads, and jobs; security; and networking.
Part 2 covers the remaining core subsystems: I/O, storage, memory management, the cache manager, and file systems. Part 2 concludes with a description of the startup and shutdown processes and a description of crash-dump analysis.
