Windows Hardware Engineering Conference (commonly known as WinHEC and later known as Windows Hardware Engineering Community) is a series of trade shows and workshops hosted by Microsoft, primarily focused on Windows-based hardware. It started from 1992 and was ran until 2008. After a seven-year absence, WinHEC returned in 2015 as technical conferences.
WinHEC is notable for its many demonstrations involving pre-release builds of Windows, including "Longhorn" build 4015 in 2003, Windows Server 2008 build 5340 in 2006, and Windows 7 build 6937 in 2008.
WinHEC was a sister event to the Microsoft Professional Developers Conference.
