What accessibility features are provided with Windows Vista operating system?
Some individuals with disabilities require assistive technology (AT) in order to access computers. Hundreds of Windows AT third-party products are available, making it possible for almost anyone to use Windows® applications, regardless of their disabilities. The Microsoft Windows operating systems also provides a core set of basic accessibility features and AT applications, which can be deployed on all computers in a computer lab or classroom without additional cost. These applications provide students with basic accessibility features from any workstation, maximizing the inclusiveness of the learning environment.
It should be noted that the AT applications that are bundled with Windows provide only a minimum level of accessibility, not the full set of features that many users require for equal access to the operating system and other software applications. Therefore, many educational entities deploy the standard set of Windows AT on all workstations by default, but additionally 1) provide a small number of dedicated workstations that are equipped with commonly requested third party AT, and 2) are prepared to purchase and install additional AT as needed by specific students.
It should also be noted that the availability of AT does not itself guarantee accessibility. Software applications must be designed in a way that is compatible with AT and other accessibility features of the operating system. For information about purchasing software products that are accessible, see the article How can I tell whether a software application is accessible?
