Internet Explorer's 27-Year Run Officially Ends on June 15, 2022
Microsoft retired the Internet Explorer 11 desktop application in favor of Edge, while quietly preserving IE-dependent legacy compatibility through Edge's own IE mode for years afterward.
Microsoft officially retired the Internet Explorer 11 desktop application on June 15, 2022, for supported versions of Windows 10 — the formal end of a browser that, in its earlier versions, had once dominated web browsing so completely it became the subject of antitrust action, closing out a story that stretched back to Internet Explorer’s original 1995 debut.
What actually happened on the retirement date
From June 15, 2022 onward, the IE11 desktop application stopped receiving support and was progressively redirected to Microsoft Edge for users who attempted to launch it, on the specific Windows 10 versions the retirement applied to. This wasn’t a removal of the underlying rendering engine entirely — it was specifically the end of IE as a standalone, separately maintained browser application.
The identity crisis behind the eventual retirement
Internet Explorer’s decline had been underway for well over a decade before this official end date — Microsoft had already released Edge as IE’s intended successor back in 2015 alongside Windows 10, and had spent years afterward encouraging both consumers and enterprises to migrate away from IE, which by the 2020s was serving primarily as a legacy compatibility fallback for older intranet applications and websites built against IE-specific quirks, rather than as a genuinely current browser most people chose deliberately.
Why full removal wasn’t actually the plan
Despite the retirement of the standalone IE11 application, Microsoft was explicit that this wasn’t meant to strand organizations still depending on genuinely IE-specific legacy web applications — a real and substantial category, particularly for large enterprises and government systems with internal tools built years or decades earlier against IE’s specific rendering behavior. The solution was Internet Explorer mode within Microsoft Edge itself: a compatibility mode that renders pages using IE’s legacy engine directly inside the modern Edge browser, officially supported through at least 2029 at the time of the retirement announcement — giving organizations a multi-year runway to actually migrate away from IE-dependent internal tooling, rather than facing an abrupt compatibility cliff.
Why this staged approach mirrored other major Microsoft deprecations
The IE-to-Edge transition followed a similar shape to other significant Microsoft platform transitions: rather than an abrupt cutoff, the actual underlying legacy capability (IE’s rendering engine) remained available and supported for a clearly bounded, multi-year period through IE mode, while the separately-maintained standalone application was what actually went away on the announced date. This let Microsoft simplify its browser engineering investment around Edge going forward, without immediately breaking whatever legitimate legacy dependency still existed across its enterprise customer base.
The broader symbolic weight of the moment
Beyond the practical mechanics, Internet Explorer’s retirement carried real symbolic significance for anyone who’d followed web history — IE had been central to the “browser wars” of the late 1990s, was the subject of a landmark antitrust case over its bundling with Windows, and for a long stretch of the early 2000s was simply how the overwhelming majority of the world accessed the web, for better and for considerably worse given its later reputation for lagging web standards support. Its quiet retirement, redirecting users to a Chromium-based Edge that shared little beyond the name with IE’s original Trident rendering engine, closed out that specific chapter of browser history definitively.
The lasting outcome
Edge, rebuilt on the Chromium engine since 2020, became Microsoft’s sole actively developed browser going forward, with IE mode serving as the deliberately time-bounded bridge for legacy compatibility rather than a permanent parallel option — a clean, if long-delayed, resolution to a browser identity that had been in transition for the better part of a decade before the actual retirement date arrived.
