Six Years, One Browser, Zero Dignity: The Agonizing Death March of Internet Explorer

There's a particular kind of corporate death that happens in slow motion — the kind where everyone in the room can see it coming, the patient is clearly not getting better, and yet somehow the plug remains stubbornly, defiantly, almost philosophically unplugged. That was Internet Explorer from roughly 2016 to 2022. A browser so deeply embedded in enterprise America's nervous system that killing it required less of a decision and more of an exorcism.

Welcome to the IE Retirement Speedrun — except it wasn't a speedrun at all. It was the opposite of a speedrun. It was a speedrun where someone set the controller down, went to make a sandwich, came back, made a different sandwich, argued about the sandwich on a Slack channel for three years, and then finished the level.

The Beginning of the End (That Wasn't Really the End)

Let's set the clock back to 2016. Microsoft, having already released Edge with the Windows 10 launch in 2015, began quietly signaling that IE's days were numbered. The company announced it would only support IE 11 going forward, dropping older versions from receiving security patches. Developers everywhere exhaled. Briefly.

Because here's the thing about enterprise software: nobody actually listens to those announcements. The Fortune 500 companies, the government agencies, the healthcare portals running on IE 7 compatibility mode — they nodded politely and then went right back to their business-critical intranet applications that could only render correctly in a browser first released when "Gangnam Style" was still three years away from existing.

Microsoft's 2016 move was the equivalent of announcing you're leaving a party at 9 PM and then still being there at 2 AM explaining to someone why you really do have to go.

The Edge Pivot That Changed Nothing (At First)

By 2019, Microsoft made a move that, in retrospect, was either genius or surrender depending on your mood: they rebuilt Edge on Chromium, the same open-source engine powering Google Chrome. The new browser, dubbed "Chromium Edge" or "the new Edge" by people who didn't want to have a whole conversation about it, launched in January 2020.

This was Microsoft essentially admitting that building a competitive browser engine from scratch was a problem they no longer wanted to have. Developers cautiously celebrated. Chrome extension compatibility! Actual DevTools! A browser that didn't treat CSS Grid like a personal attack!

But IE 11 was still there. Still installed. Still lurking in enterprise environments like that one coworker who technically put in their two weeks but keeps showing up to meetings anyway.

The new Edge even shipped with an "IE Mode" — a feature that let users render specific sites using the old Trident engine inside the new browser. On paper, this was a graceful migration path. In practice, it was Microsoft strapping IE's brain into Edge's body like some kind of browser Frankenstein, and then telling IT departments, "See? It's fine. It's basically the same."

2021: The Death Date Gets a Date

In May 2021, Microsoft finally did it. They announced that Internet Explorer 11 would reach end-of-life on June 15, 2022. A real date. A calendar date. Something you could put in a countdown widget.

The developer community reacted the way you'd expect a group of people to react upon learning that the thing that had been ruining their lives for a decade would finally stop existing: with memes. Glorious, cathartic, slightly unhinged memes. Twitter (still called Twitter then, a simpler time) erupted. GitHub repositories appeared with names like "Drop IE 11" checklists. Blog posts multiplied. Developers who had spent years writing filter: progid:DXImageTransform.Microsoft.gradient into their CSS allowed themselves, for one shining moment, to feel hope.

For those uninitiated in the suffering: supporting IE 11 meant no CSS Grid without workarounds, no ES6 modules without transpiling everything through Babel, no fetch API without polyfills, no <details> element, no CSS custom properties, and a general sense of spiritual malaise that settled over every front-end developer like a fog. Dropping IE support wasn't just a technical decision — it was a vibe shift.

The Corporate Clients Who Didn't Get the Memo

Here's where the story gets genuinely funny, if by "funny" you mean the kind of thing you laugh at while also staring at the ceiling at 2 AM.

Microsoft's announcement didn't mean companies immediately stopped using IE. Because they couldn't. Or wouldn't. The distinction, at enterprise scale, is largely academic.

Banks. Insurance portals. State government websites. Internal HR systems built in 2007 by a contractor who has since retired to Florida and is unreachable. These systems didn't care about Microsoft's sunset timeline. They had their own timelines, governed by procurement cycles, compliance requirements, and the immovable will of someone in IT who remembered the last migration and had no desire to do another one.

Developers working on public-facing products faced a particular flavor of absurdity: their companies would announce IE support was being dropped, only to receive one urgent email from a client whose entire accounts payable workflow ran through an IE-only web application. The roadmap would get quietly pushed. IE support would get quietly maintained. The developer would quietly update their resume.

June 15, 2022: The Day It Actually Happened

And then, like a fever finally breaking, it was over. On June 15, 2022, Microsoft officially retired Internet Explorer 11. The browser would redirect users to Edge. Downloads were pulled. Support ended.

The internet held a small, sincere funeral. There were tribute threads and farewell posts with an emotional register that hovered somewhere between genuine nostalgia and the relief of a root canal finally being finished. Even people who had cursed IE's name for their entire professional careers found themselves feeling something — not quite sadness, but the particular melancholy of watching an era actually close.

For developers who had built their careers in the late 2000s and 2010s, IE wasn't just a browser. It was the antagonist that sharpened their skills. Every CSS hack, every conditional comment, every browser detection snippet represented a small act of professional problem-solving. IE made developers better engineers the way a leaky roof makes you a better roofer — through sustained, unavoidable suffering.

The Legacy Nobody Asked For (But Everyone Has)

The irony that Microsoft's own Teams application had dropped IE 11 support almost a full year before the official retirement date tells you everything you need to know about how the sunset actually went. The company was essentially racing against itself.

Today, IE Mode in Edge keeps the Trident engine technically alive for enterprise use through at least 2029 — which means the browser never fully died so much as it got transferred to a very specific assisted living facility with strict visiting hours.

Dropping IE support from a legacy codebase remains, to this day, a rite of passage. The moment a developer opens a pull request titled "Remove IE11 polyfills and workarounds" and watches hundreds of lines of defensive, apologetic code disappear — that's a moment. That's growth. That's closure.

We're still loading since 1995 here at Internet Explorer Tan. But at least now, when the page finally renders, it uses CSS Grid.

Rest in deprecated peace, IE. You were the worst. We kind of miss you.
