Microsoft is retiring Internet Explorer on June 15, 2022, after more than 25 years, in favor of Edge.
Internet Explorer used to be the top browser during the explosion years of the internet but has largely been unused by consumers for years. While the Long-Term Servicing Channel (LTSC) of Windows 10 will still include Internet Explorer next year, all consumer versions will end support of the browser. Although consumers haven't really been using IE, many business still rely on it. The alternative for most businesses will be Microsoft Edge with IE mode, which allows businesses to adopt Edge for older legacy websites. IE mode supports older ActiveX controls and legacy sites. Microsoft is promising to support IE mode in Edge until through at least 2029. Link
