Windows NT Embedded 4.0

Windows NT Embedded 4.0 (often shortened to NTe, codenamed Impala) is a componentized version of Windows NT Workstation 4.0 intended for use in embedded units. It was released on 30 August 1999.

Unlike any other installation of Windows, which you would install by booting into its installation media and then simply setting it up, Windows NT Embedded 4.0 is instead built and deployed with a tool called Target Designer, which is bundled alongside Component Designer into Windows NT Embedded 4.0's installation media. Although Component Designer can be used for certain purposes, only Target Designer is needed for a regular Windows NT Embedded 4.0 image.

There are 3 configurations bundled by default in Target Designer. The utility may also be used to create custom configurations which define different features such as drivers, shell settings, applications included, etc.

After the release of Windows XP Embedded, mainstream support for Windows NT Embedded 4.0 ended on June 30, 2003, followed by extended support on July 11, 2006, with Windows 98 and Windows Me ending support on that date as well.
