Microsoft stopped supporting the Internet Explorer web browser on Wednesday, indicating the end is near for a 26-year-old brand with baggage that includes an antitrust case, security flaws and lagging performance. Users will instead be pointed to Microsoft’s newer Edge browser.

While Microsoft doesn’t derive revenue directly from browsers, Edge defaults to the company’s Bing search engine, through which the software and hardware maker generates advertising revenue. That category represents about 6% of Microsoft’s total revenue, at nearly $3 billion in the first quarter.

Microsoft won’t offer technical support or security updates to customers as it focuses more on Edge, a browser that’s available on mobile devices, Mac and even Linux, rather than being confined to Windows. Microsoft released Edge as part of Windows 10 in 2015, to exist alongside Internet Explorer as something new and efficient yet similar to what Windows users already knew.

Internet Explorer still has a small group of devotees, though, in part because it remains the only way to reach certain corporate web applications. It won’t be vanishing yet, even though it’s being retired.

“Over the next few months, opening Internet Explorer will progressively redirect users to our new modern browser, Microsoft Edge with IE mode,” Sean Lyndersay, a general manager at the company, wrote in a blog post. “Users will still see the Internet Explorer icon on their devices (such as on the taskbar or in the Start menu) but if they click to open Internet Explorer, Microsoft Edge will open instead with easy access to IE mode. Eventually, Internet Explorer will be disabled permanently as part of a future Windows Update, at which point the Internet Explorer icons on their devices will be removed.”

A “Reload in IE mode” button will appear in the Edge toolbar, and the browser will ask people if they’d like to open a page in IE mode next time, Lyndersay wrote.

“Microsoft Edge will also check in with the user every 30 days to make sure they still need IE mode for the site,” he wrote. “As more and more sites get updated to modern standards, users will need to use IE mode less and the modern rendering engine more.”

A brief history of Internet Explorer

In 1995, the web quickly became a high priority for Microsoft. Then-Microsoft CEO Bill Gates declared in a memo that web developments “will set the course of our industry for a long time to come.” Microsoft bundled Internet Explorer in the Windows 95 operating system free of charge. It quickly took hold.

Internet Explorer took a commanding lead in browser market share thanks to its inclusion in Windows, the world’s most widely used PC operating system. The strategy helped Microsoft undercut the then up-and-coming Netscape Communications’ Navigator browser.

When the U.S. Justice Department filed its landmark antitrust case against Microsoft in 1998, the federal agency described the bundling of Internet Explorer in Windows 95 as an “illegal tie-in.” The company changed the terms of its agreements with device makers to allow them to remove icons for the browser from Windows if they want to show off other browsers.

Other issues hurt the reputation of Internet Explorer, too. A security expert said in 2004 that it was “foolish” to use the browser. The Washington Post published an article under the headline “Internet Explorer Unsafe for 284 Days in 2006.” In 2014, following the disclosure of one flaw, the U.S. Department of Homeland Security said that those who can’t follow Microsoft’s advice for mitigation ought to consider using another browser.

Internet Explorer didn’t always deliver the best performance. The speed of Chrome particularly impressed observers when it appeared in 2008. That was by design. When Google came up with the values for Chrome, it chose three S’s: speed, stability and security, said Aaron Boodman, a former Chrome engineering manager.

The performance difference with Internet Explorer is clear to this day. Its handling of the widely used HTML5 markup language can’t keep up with Chrome, Edge or Apple’s Safari.

Digital preferences changed over a quarter-century. The smartphone became a companion for billions of people, and in 2012 Google won the upper hand in the browser wars with Chrome.

In 2020, Microsoft released a new version of Edge that relies on Chromium, the open-source project behind Google’s Chrome browser, and it came with Internet Explorer mode, enabling enterprise workers to access websites designed for the Internet Explorer in Edge. Last year, Microsoft advised consumers to move from Internet Explorer to Edge. Now the company is further diminishing the presence of its original browser.

Now Microsoft wants to make sure the people who are still using Internet Explorer will move to Edge, which holds about 4% share, according to data from privately held StatCounter. The company will move favorites, passwords and settings from Internet Explorer into Edge, Lyndersay wrote. Edge is, he said, “the best browser for Windows.”
