Showstopper! is a vivid account of the creation of Microsoft Windows NT, perhaps the most complex software project ever undertaken. It is also a portrait of David Cutler, NT's brilliant and, at times, brutally aggressive chief architect.

Cutler surely ranks as one of the most impressive software engineers the field has ever produced. After leading the team that created the VMS operating system for Digital's VAX computer line--an accomplishment that most would regard as a lifetime achievement--he went on to conceive and lead the grueling multi-year project that ultimately produced Windows NT. Both admired and feared by his team, Cutler would let nothing stand in the way of realizing his design and often clashed with his programmers, senior Microsoft management, and even Gates himself. Yet no matter how involved he became in managing his 100-programmer team, he continued to immerse himself in every technical detail of the project and write critical portions of the code himself.

Showstopper! is also a fascinating look at programmer and managerial culture behind the Microsoft facade. The portraits of the men and women who created NT not only reveal the brilliance of their work but the crushing stress and the dislocating effects that new wealth had on their lives. For some team members, the NT project ultimately destroyed their marriages, friendships, and virtually every human relationship outside of work. Showstopper! also reveals the uncertainties, false starts, and blind alleys that dogged the project as Microsoft repositioned NT from an improved OS/2 to something that would ultimately challenge both OS/2 and Unix for the title of the world's most powerful operating system.
