Microsoft began work on Windows Vista, known at the time by its codename Longhorn, in May 2001, five months before the release of Windows XP. It was originally expected to ship sometime late in 2003 as a minor step between Windows XP and Blackcomb, which was planned to be the company's next major operating system release.Security Essentials
