Intended to be the revolutionary successor to Windows XP, Longhorn promised a radical reimagining of the personal computer. Instead, feature creep, unstable code, and development chaos forced Microsoft to hit the reset button in 2004, scrapping years of work to build what eventually became Windows Vista.
