G. Pascal Zachary managed to get total access to the formerly unseen programming catacombs of Microsoft and has made the most of it with this riveting look inside one of the world’s most fascinating corporations. He traces the tumultuous creation of Windows NT, capturing not only the technical ambition but the human drama at its core. By illuminating the passions, conflicts, and relentless drive of Dave Cutler’s team, Zachary offers a rare window into a crucible where modern computing was forged.

Windows NT was one of the most important pieces of software ever written for the personal computer.  When Microsoft introduced Windows NT in 1993, historians took little note of it-- we thought it was just another incremental product. Now, decades later, we realize that Windows NT, along with the Intel Pentium processor introduced at the same time, transformed the place of the personal computer in the computing world. G. Pascal Zachary takes us inside Microsoft to observe the drama and creativity that brought this piece of code to life. Zachary managed to get total access to the formerly unseen programming catacombs of Microsoft and has made the most of it with this riveting look inside this fascinating technology titans.

Like the software whose creation it chronicles, Zachary’s book is an exercise in persistence and detail. We learn every twist and turn in the lives of the people who sacrificed family and friends to create Windows NT. We sweat over every major bug that threatens to undo the program. More than anything else, we come to appreciate what a miracle software really is: a unique blend of artistry and drudgery, mathematical order and creative chaos.

Often compared favorably to the better-known digital creation story, Soul of the New Machine, Showstopper has its own fervent fans. One such admirer, the prize-winner economics writer David Warsh, insists, “I remain very enthusiastic about Showstopper, which is better than Soul of a New Machine. Zachary’s unique book richly deserves a new edition.”

Part of the uniqueness of Zachary’s software creation story: he had incredible access to the actors in this drama. He was able to interview all of the major players involved in NT development, including David Cutler, the project’s lead, and Bill Gates, the CEO of Microsoft at the time. It provides real insight into the market landscape at the time, the challenges that Windows NT faced, and what it was like for regular software developers and management to laboriously crank out NT over many sleepless nights throughout a period of roughly four years.
