If you have difficulty using a mouse or typing, have slightly impaired vision, or are deaf or hard of hearing, you can adjust the appearance and behavior of Windows 7 to make your computer easier for you to use. The Ease of Access Center helps you configure Windows for your vision, hearing, and mobility needs. You can also answer a few questions about your daily computer use that can help Windows recommend accessibility settings and programs for you. To open the Ease of Access Center, click the Start button on the taskbar, click Control Panel, click Ease of Access and then click Ease of Access Center. To use the Ease of Access questionnaire, click Get recommendations to make your computer easier to use. The Ease of Access Center provides utilities to adjust the way your keyboard, display, and mouse function to suit various vision and motor abilities. Some of the accessibility tools available include Magnifier (New!), On-Screen Keyboard, Narrator, and High Contrast. You can also set accessibility options, such as StickyKeys, FilterKeys, ToggleKeys, Sound-Sentry, ShowSounds, and MouseKeys, that automatically turn off accessibility features, provide warning sounds, and determine when to apply the settings. The accessibility tools in Windows are intended to provide a low level of functionality for those with special needs. If these tools do not meet your daily needs, you might need to purchase a more advanced accessibility program.
