IE 11 will be retired for Windows 10 client SKUs (version 20H2 and later) and Windows 10 IoT (version 20H2 and later). Products not affected by this retirement include IE Mode in Edge; IE 11 desktop on Windows 8.1, Windows 7 (with Extended Security Updates), Windows Server LTSC (all versions), Windows Server 2022, Windows 10 client LTSC (all versions), Windows 10 IoT LTSC (all versions). The IE 11 desktop app is not available on Windows 11, as Edge is the default browser for Windows 11.
Microsoft officials say support for IE Mode will follow the lifecycle of current and future Windows client, Server, and IoT releases at least through 2029. If support for a version of Windows ends before 2029, support for IE Mode on that version also will end. Microsoft has committed to providing a one-year notice ahead of retiring IE Mode. Officials have said that there will be no extensions for IE 11 support past the stated retirement dates.
Microsoft rolled out the very first version of IE in 1995, alongside Windows 95. It introduced IE 11 in October 2013. Microsoft began bundling Edge with Windows 10 in 2015.
