Hands-On Experiments

Even without access to the source code, much can be gleaned about Windows internals from available tools such as the kernel debugger. When a tool can be used to expose or demonstrate some aspect of Windows internal behavior, the steps for trying the tool yourself are listed in "Experiment" boxes. These appear throughout the book, and we encourage you to try these as you're reading—seeing visible proof of how Windows works internally will make much more of an impression on you than just reading about it will.

Topics Not Covered

Windows is a large and complex operating system. This book doesn't cover everything relevant to Windows internals but instead focuses on the base system components . For example, this book doesn't describe COM+, the Windows distributed object-oriented programming infrastructure, or the .NET Framework, the foundation of the next generation of managed code applications.

Because this is an internals book and not a user , programming, or system administration book, it doesn't describe how to use, program, or configure Windows.

A Warning and Caveat

Because this book describes undocumented behavior of the internal architecture and operation of the Windows operating system (such as internal kernel structures and functions), this content is subject to change between releases. (External interfaces, such as the Windows API, are not subject to incompatible changes.)

By "subject to change," we don't necessarily mean that details described in this book will change between releases, but you can't count on them not changing. Any software that uses these undocumented interfaces might not work on future releases of Windows. Even worse , software that runs in kernel mode (such as device drivers) and uses these undocumented interfaces might experience a system crash when running on a newer release of Windows.

Every effort has been made to ensure the accuracy of this book. Should you run into any problems or issues, please refer to the sources listed below.
