Make Your Computer Easier to Use (Ease of Access Center)
The Ease of Access Center is a central location where you can turn on and set up accessibility settings and programs available in Windows. You can adjust settings that make it easier to see your computer, use the mouse and keyboard, and use other input devices. You can also answer a few questions about your daily computer use and accessibility requirements and have Windows recommend settings and programs for you.
Figure 1: Ease of Access Center: Make your computer easier to use
The Ease of Access Center is available through a Control Panel icon, and can be opened by selecting the Start button , clicking Control Panel, clicking Ease of Access, and then clicking  Ease of Access Center. You can also press the Windows logo key  +U and the Ease of Access Center will open. The Ease of Access Center includes:
Quick access to common tools
Start Narrator, Magnifier, On-Screen Keyboard, and High Contrast quickly from Quick access to common tools in the Ease of Access Center. When you start these tools from the Quick Access section, the tools will turn off after you log off or shut down. If you want these tools to start automatically every time you log on, turn them on under the Explore all settings categories.
Get recommendations to make your computer easier to use
This optional questionnaire provides a personalized list of recommended settings that can improve your ability to see, hear, and comfortably use your computer. The Ease of Access Center questionnaire takes the guesswork out of selecting settings. Based on your answers to a series of questions about routine tasks, a custom list of recommended settings is provided so you can choose which options you want to try. You can complete the questionnaire and adjust your settings as often as you like. You can find the questionnaire in the Ease of Access Center (in Control Panel) by selecting Get recommendations to make your computer easier to use.
Explore All Settings
Instead of looking for accessibility settings in various places on your computer, Windows 7 brings all those settings together and organizes them into categories that you can explore in the Ease of Access Center. You can explore seven different categories of accessibility settings and programs:
Use the computer without a display 7
Make the computer easier to see 9
Use the computer without a mouse or keyboard 11
Make the mouse easier to use 13
