Windows Internals, Sixth Edition is intended for advanced computer professionals (both developers and system administrators) who want to understand how the core components of the Microsoft Windows 7 and Windows Server 2008 R2 operating systems work internally. With this knowledge, developers can better comprehend the rationale behind design choices when building applications specific to the Windows platform. Such knowledge can also help developers debug complex problems. System administrators can benefit from this information as well, because understanding how the operating system works “under the covers” facilitates understanding the performance behavior of the system and makes troubleshooting system problems much easier when things go wrong. After reading this book, you should have a better understanding of how Windows works and why it behaves as it does.

The Windows I/O system consists of several executive components that together manage hardware devices and provide interfaces to hardware devices for applications and the system. In this chapter, we’ll first list the design goals of the I/O system, which have influenced its implementation. We’ll then cover the components that make up the I/O system, including the I/O manager, Plug and Play (PnP) manager, and power manager. Then we’ll examine the structure and components of the I/O system and the various types of device drivers. We’ll look at the key data structures that describe devices, device drivers, and I/O requests, after which we’ll describe the steps necessary to complete I/O requests as they move through the system. Finally, we’ll present the way device detection, driver installation, and power management work.
