Microsoft Agent is a technology developed by Microsoft that allows for users to interact with animated characters inside applications and web pages. It used text to speech engines to allow the animated characters to speak to the end user. These animated characters were called "Microsoft Agents". It came preinstalled with Windows beginning with Windows 2000, though it was first incorporated into a build of Windows with Windows 98 build 1569. Microsoft Agent continued to release alongside all Windows versions until Windows 7 in 2009, following Microsoft's discontinuation of Microsoft Agent. The latest major release of Microsoft Agent was version 2.0 on October 12th, 1998.
