 Windows NT Embedded 4.0 got its start in 1998 with a small team of developers at Microsoft.This project, known within Microsoft as Impala, was released in 1999 as Windows NT Embedded 4.0—a set of tools and a database of approximately 250 components that allowed developers to put together small Windows NT 4.0 run-time images for embedded devices.The tools allowed OEMs and embedded developers to create components encapsulating their binaries, and to add them seamlessly into Windows NT Embedded runtimes containing limited functionality and devices.
