Old Internet Explorer Browsers Discontinued

Microsoft announced this week that older versions of Internet Explorer (IE) have been discontinued. In Microsoft’s official terms, the old IE browsers have reached the “end of life” and must be upgraded to receive support from the company. Support has officially ended for Internet Explorer versions 8, 9, and 10. A final patch of security updates was released this week, but no additional security updates, bug fixes, or other patches will be released for these versions. Microsoft is encouraging users of the older versions of Internet Explorer to upgrade to the latest versions at no cost in order to receive support. These versions of IE still work, and can still be used, but they will not be supported, and if bugs or security flaws are discovered, they will not be fixed. Users of these older browsers should upgrade to IE 11, or if Windows 10 is installed, the browser Edge is provided as part of the most recent operating system. In Windows 10, Edge is the replacement for Internet Explorer. With this announcement from Microsoft, IE 11 and Edge are the only two browsers being supported by Microsoft.

Market Share of discontinued Internet Explorer Versions

The market share of Internet Explorer versions that have been discontinued and are impacted by this announcement is approximately 20 percent of all web traffic. Of all Internet traffic, IE version 8 has a 9 percent market share, while IE 9 has 7 percent, and IE 10 garners 4 percent.

IE Versions for usability and UX testing

Even with the older versions of Internet Explorer being termed end-of-life, UX and web designers may still need to use older versions of IE for usability testing purposes. Use data from web analysis such as Google Analytics to see the browsers being used by visitors to a site. Any browser that is used by more than 5% of site visitors should be tested to make certain users are able to effectively navigate and use a site. These UX testing considerations and processes are covered in the UX design principles class and other UX courses that address usability testing processes.

Why IE users should upgrade to IE11 or Edge

There are several key reasons that users of Internet Explorer should upgrade their browser. The most important reason to upgrade IE is access to security patches which reduce the risk of viruses. Newer browsers also reduce the risk of malicious attacks on a computer which compromises security, and can lead to the theft of data. Organizations that are regulated also may want to upgrade from older versions in order to remain compliant with privacy and security laws, which IE8 may not support. Older browsers do not support access to modern websites that use HTML5 and CSS3, while these are supported more fully with IE11 and Edge.
