This training course is a combined, reformatted, improved, and modernized version of the two previous books (x64) Windows Debugging: Practical Foundations, that drew inspiration from the original lectures we developed almost 18 years ago to train support and escalation engineers in debugging and crash dump analysis of memory dumps from Windows applications, services, and systems. At that time, when thinking about what material to deliver, we realized that a solid understanding of fundamentals like pointers is needed to analyze stack traces beyond a few WinDbg commands. Therefore, this book is not about bugs or debugging techniques but about the background knowledge everyone needs to start experimenting with WinDbg and learn from practical experience and read other advanced debugging books. This body of knowledge is what the author of this book possessed before starting memory dump analysis using WinDbg 18 years ago, which resulted in the number one debugging bestseller: multi-volume Memory Dump Analysis Anthology. Now, in retrospection, we see these practical foundations as relevant and necessary to acquire for beginners as they were 18 years ago because operating systems internals, assembly language, and compiler architecture haven’t changed much in those years.

The book contains two separate sets of chapters and corresponding illustrations. They are named Chapter x86.NN and Chapter x64.NN respectively. The new format makes switching between and comparing x86 and x64 versions easy. Both sets of chapters can be read independently. We included x86 chapters because many 3rd-party Windows applications are still 32-bit and executed in 32-bit compatibility mode on x64 Windows systems.

Almost 5 years have passed since the first edition of the combined training course that used the earlier version of Windows 10. Since then, we have also published Practical Foundations of Linux Debugging, Disassembling, Reversing and Practical Foundations of ARM64 Linux Debugging, Disassembling, Reversing books. At that time, we thought about revising our Windows course. Since then, Windows 11 appeared, and we also added Docker support for most of our Windows memory dump analysis courses. While working on the Accelerated Windows Debugging 4D course, we decided to make the second edition of Practical Foundations of Windows Debugging based on WinDbg from Windows 11 SDK and Visual Studio 2022 build tools and an optional Docker support for the exercise environment. We also changed the

The book is useful for:

• Software technical support and escalation engineers;

• Software engineers coming from managed code or JVM background;

• Software testers;

• Engineers coming from non-Wintel environments;

• Windows C/C++ software engineers without assembly language background;

• Security researchers without x86/x64 assembly language background;

• Beginners learning Windows software reverse engineering techniques;

This introductory training course can complement the more advanced course Accelerated Disassembly, Reconstruction and Reversing, Revised Edition. It may also help with advanced exercises in Accelerated Windows Memory Dump Analysis books. This book can also be used as an Intel assembly language and Windows debugging supplement for relevant undergraduate-level courses.
