WindowsWindows Operating Systems include Narrator, a free pre-installed screen reader software. Although Narrator is included with all Windows computers, it is a basic screen reader that is not compatible with many software applications. Most Windows users prefer a more advanced screen reader, JAWS.
Released in 1989, one of the most widely used commercial screen readers is JAWS - Job Access with Speech. It is a program used by Microsoft Windows and reads the screen with a text-to-speech synthesizer or refreshable Braille display. It is used at the University of Illinois.
Another screen reader for Windows users is NVDA - NonVisual Desktop Access. NVDA is free and open-source; thus, it provides access to technology at no extra cost for blind and vision impaired users.
