I fell asleep with my laptop in front of me the other night and noticed when I woke up that everything I typed was being repeated by some computer sounding voice on my laptop called Sam. Turns out I had accidentally turned on Microsoft Narrator by hitting the Win-Key + U. This utility is one of a couple of others including Microsoft Magnifier that are managed by the Microsoft Utility Manager. Depending on the operating system these utilities run in different ways and the below article is based on Windows XP Pro though turning it off is similar on other Windows versions as well. I believe in Windows 2000 the Utility Manager actually runs as a service so the service can be disabled in the Services Manager.
