Microsoft is committed to making its products and services easier for everyone to use. This section provides information about the following products and services, which make Microsoft Windows NT Workstation more accessible for people with disabilities:

Through a text telephone (TT/TDD) service, Microsoft provides users who are deaf or hard-of-hearing with complete access to Microsoft’s product and customer support services.

Windows NT includes several accessibility features that provide users who are movement or hearing disabled with better access to computers that run Windows NT. These features enable you to change your display, mouse, and keyboard features, as well as use sound to help you use Windows most effectively.

For example, if you have trouble using a mouse, you can use the MouseKeys feature, which enables you to use the numeric keypad to move the mouse pointer.

To find these features, double-click the Accessibility Options icon in Control Panel. For a more detailed list of procedures, look up "accessibility" in the Help Index.

To use Accessibility Options shortcut keys, the shortcut keys must be enabled. For more information, look up "accessibility" in the Help Index.

It is not possible to run the Windows NT installation program in standard mode concurrently with third-party accessibility utilities such as screen readers or screen magnifiers. Users who require accessibility utilities such as these can use the installation program’s Unattended Setup mode from a command line. The Unattended Setup mode installs Windows NT without requiring any user interaction. It can also be used to install an accessibility utility automatically at the same time. For complete instructions, see the file ACCSETUP.TXT on your installation disk.

There are many ways you can adjust the appearance and performance of Windows NT, your mouse, and your keyboard to suit varying vision and motor abilities without requiring any additional software or hardware. Application note WW1279 describes the specific methods.

If you have a modem, you can download application notes from the following network services:

Microsoft distributes Dvorak keyboard layouts that make the most frequently typed characters on a keyboard more accessible to people who have difficulty using the standard "QWERTY" layout. There are three Dvorak layouts: one for two-handed users, one for people who type with their left hand only, and one for people who type with their right hand only. The left-handed or right-handed keyboard layouts can also be used by people who type with a single finger or a wand. You do not need to purchase any special equipment to use these features.

Microsoft Windows NT already supports the two-handed Dvorak layout, which can be useful for coping with or avoiding types of repetitive-motion injuries associated with typing. For a detailed list of procedures, look up "Dvorak" in the Help Index.
