This is a comprehensive guide to modern x64 assembly programming on Windows, designed for experienced C/C++ developers and motivated beginners who want to understand what happens at the lowest level of software execution. We cover everything from the x64 register file and calling convention through SIMD vectorization, PE format internals, structured exception handling, multithreading, reverse engineering, optimization techniques, debugging strategies, and secure coding practices. Each chapter builds on the last, with annotated code examples, practical projects, and exercises to reinforce your understanding. By the end, you will have a deep mental model of how x64 Windows programs execute and the skills to write high-performance, secure low-level code.
