In 1988, Microsoft chief Bill Gates launched an extraodinary campaign to ensure his company's domination of the next generation of the computer revolution. Under programming legend David Cutler, he assembled a team of programmers who worked day and night for five years, spending $150 million in the drive to unlock new intricacies of both computer technology and the marketplace. Windows NT was the result, a complex system capable of repeatedly and reliably working on millions of computers throughout the world. This is the story of that team and its achievement, a tale of money and power, colourful characters and clattering egos in the workplace, and an adventure on the frontiers of new technology.
