Older Versions of
Microsoft Internet Explorer

The latest versions of Internet Explorer are included in the latest versions of Microsoft Windows® operating systems for personal and business use. But, because many people with disabilities use earlier versions of the browser, the following information is provided concerning the accessibility features of those products.

If you are currently considering an upgrade of Internet Explorer or the Windows operating systems that include it, and you use an accessibility aid, it is strongly recommended that you check with the manufacturer of your accessibility aid first. See our catalog of Windows-based assistive technology.

Information about Older Versions of Internet Explorer:

• Microsoft Internet Explorer 4.01
• Microsoft Internet Explorer 4.0
• Microsoft Internet Explorer 3.0

Microsoft Internet Explorer 4.01

Internet Explorer 4.01 introduced a number of advances that made the Web more accessible to computer users with disabilities. In particular, it included features allowing customization of the appearance of Web pages to the personal needs and preferences of individuals. Internet Explorer 4.01 also included full support for Microsoft Active Accessibility®, the developer technology that helps the operating system, programs, and assistive technology communicate better.

Accessibility Features

• Full support for Microsoft Active Accessibility technology, which lets compatible assistive technology work more effectively. For example, screen readers can navigate tables and frames and read them to the user in proper order, or read the names of images displayed on the screen.
• The ability to fully display the description for each image when images aren't displayed, and to display it in your choice of colors.
• Greatly improved keyboard access to Web pages and to Help.
• The ability to move the system caret, allowing older assistive technology to read or magnify the right information when the user navigates with the keyboard.
• The ability to remove all toolbars and scrollbars from the screen, making more text visible to users who have cognitive disabilities or prefer larger fonts. Check with your assistive technology manufacturer before upgrading.

Internet Explorer version 4.01 introduced a number of new accessibility features and fixed a number of problems that existed in version 4.0. While Internet Explorer version 4.01 improved accessibility in many ways, it behaved differently than previous versions. Some accessibility products had to be updated to work properly with this version—especially if they were not yet updated to work with version 4.0.

Whenever a software upgrade is being considered, people who rely on screen readers, voice-input utilities, or other assistive technology should contact their aids product manufacturer before upgrading. Check with your assistive technology manufacturer for more information. See our guide to assistive technology catalog.
