According to the Bloomberg Billionaires List, Gates became the world's richest person again in May 2013, a position that he last held on the list in 2007. He held the position until Carlos Slim reclaimed it in July 2014. As of September 2014, he is the second richest person in the world.

During his career at Microsoft, Gates held the positions of CEO and chief software architect, he was also the largest individual shareholder up until May 2014. He has also authored and co-authored several books.

Gates is one of the best-known entrepreneurs of the personal computer revolution. Gates has been criticized for his business tactics, which have been considered anti-competitive, an opinion which has in some cases been upheld by judicial courts. In the later stages of his career, Gates has pursued a number of philanthropic endeavors, donating large amounts of money to various charitable organizations and scientific research programs through theBill & Melinda Gates Foundation, established in 2000.

Gates stepped down as chief executive officer of Microsoft in January 2000. He remained as chairman and created the position of chief software architect for himself. In June 2006, Gates announced that he would be transitioning from full-time work at Microsoft to part-time work, and full-time work at the Bill & Melinda Gates Foundation. He gradually transferred his duties to Ray Ozzie(which has since left Microsoft), chief software architect, and Craig Mundie, chief research and strategy officer. Gates's last full-time day at Microsoft was June 27, 2008. He stepped down as chairman of Microsoft in February 2014, taking on a new post as technology advisor to support newly appointed CEO Satya Nadella.

Gates was born in Seattle, Washington, in an upper-middle-class family, the son of William H. Gates, Sr. and Mary Maxwell Gates. His ancestral origin includes English, German, and Scots-Irish. His father was a prominent lawyer, and his mother served on the board of directors for First Interstate BancSystem and the United Way. Gates's maternal grandfather was JW Maxwell, a national bank president. Gates has one elder sister, Kristi (Kristianne), and one younger sister, Libby. He was the fourth of his name in his family, but was known as William Gates III or "Trey" because his father had the "II" suffix.Early on in his life, Gates's parents had a law career in mind for him. When Gates was young, his family regularly attended a Congregational church. The family encouraged competition; one visitor reported that "it didn't matter whether it was hearts or pickleball or swimming to the dock there was always a reward for winning and there was always a penalty for losing"

At the end of the ban, the four students offered to find bugs in CCC's software in exchange for computer time. Rather than use the system via Teletype, Gates went to CCC's offices and studied source code for various programs that ran on the system, including programs in Fortran, Lisp, and machine language. The arrangement with CCC continued until 1970, when the company went out of business. The following year, Information Sciences, Inc. hired the four Lakeside students to write a payroll program in Cobol, providing them computer time and royalties. After his administrators became aware of his programming abilities, Gates wrote the school's computer program to schedule students in classes. He modified the code so that he was placed in classes with "a disproportionate number of interesting girls." He later stated that "it was hard to tear myself away from a machine at which I could so unambiguously demonstrate success. At age 17, Gates formed a venture with Allen, called Traf-O-Data, to make traffic counters based on the Intel 8008 processor. In early 1973, Bill Gates served as a congressional page in the U.S. House of Representatives.

Gates graduated from Lakeside School in 1973. He scored 1590 out of 1600 on the SAT and enrolled at Harvard Collegein the autumn of 1973. While at Harvard, he met Steve Ballmer, who would later succeed Gates as CEO of Microsoft.
