Accessibility Parameters

The system maintains a set of accessibility parameters that indicate whether the user has special needs or preferences. The user controls the state of these parameters, typically using a Control Panel application. Control Panel applications or other programs that allow the user to customize the Windows environment can use the SystemParametersInfo function to set the accessibility parameters.
