    Neukom’s tenure at Microsoft began in 1978 when he was hired as the company’s first outside legal counsel. In 1985, he transitioned into an in-house role as the company’s general counsel, where he would later grow the legal department from just a handful of employees to nearly 600 by the time he retired in 2002. His legacy is cemented by his work navigating Microsoft through critical antitrust challenges, as well as his influence on the company’s culture.

    According to GeekWire, his colleagues remember Neukom not only for his legal acumen but also for his sense of fairness. Microsoft President Brad Smith, who succeeded Neukom as general counsel, highlighted Neukom’s cultural impact. “Bill established at Microsoft — and among our lawyers — a deep cultural commitment to excellence, public service, and high integrity,” Smith said in a statement.

    One of Neukom’s defining features was his emphasis on “professional independence.” While working closely with company executives like Bill Gates, he maintained a stance of independence, ensuring that the legal team provided honest counsel, even when it was difficult. “We had to tell them what they needed to know — not what they wanted to hear from us,” Neukom explained in a Microsoft Alumni Network interview.

    Neukom’s leadership was crucial in guiding Microsoft through its initial public offering in 1985, but his most prominent role came during the company’s legal battles over antitrust concerns. The company faced serious scrutiny from both the U.S. Federal Trade Commission and the Department of Justice. Neukom, however, remained firm in his belief that Microsoft’s actions were legal, fair, and beneficial for consumers. His resistance to government efforts aimed at breaking up the company became a hallmark of his tenure. As GeekWire notes, despite growing pressure, Microsoft’s leadership, including Gates and Neukom, never settled on terms that would restrict the company’s ability to innovate.

    The culmination of these efforts was a consent decree with the DOJ, allowing Microsoft to remain intact, but the prolonged antitrust battles ultimately distracted the company from fully capitalizing on emerging technologies like the internet and mobile devices during a transformative period in the tech world.

    Beyond his work with Microsoft, Neukom’s contributions to technology law were foundational. He was instrumental in establishing intellectual property rights for software and shaping how the tech industry approached software licensing. His influence extended beyond Microsoft’s walls, playing a key role in the broader tech and legal communities.

    After retiring from Microsoft, Neukom continued to make significant contributions to both law and society. He chaired his former law firm, K&L Gates, from 2003 to 2007 and served as president of the American Bar Association from 2007 to 2008. In addition, he founded the World Justice Project, an organization dedicated to promoting the rule of law worldwide. According to GeekWire, Neukom’s legacy as a leader in law and justice lives on through his many contributions.

    In an unexpected move, Neukom also served as CEO of the San Francisco Giants baseball team from 2008 to 2011, where he oversaw their World Series victory in 2010. This foray into sports leadership showcased his versatility and leadership style, which had defined his legal career.

    Microsoft’s Brad Smith summed up the sentiment of many who worked with Neukom: “The values established by Neukom at Microsoft continue to define our work more than two decades after his retirement. We will miss him, especially as we reflect on how we benefited from his leadership.”
