Internet Explorer 11

Internet Explorer 11 is the last version of Internet Explorer. It was released on 17 October 2013 and shipped alongside Windows 8.1. An update was later made available for Windows 7 Service Pack 1. An official build of Internet Explorer 11 is not available for Windows 8 as it was intended to be used to promote the Windows 8.1 upgrade. However, Microsoft released Internet Explorer 11 for Windows Server 2012 and Windows Embedded 8 on 16 April 2019 via Windows Update as a regular Desktop application without the Metro interface. Internet Explorer 11 is also part of Windows 10, however, it is not set as the default browser to promote the Microsoft Edge browser. A feedback button (in the form of a smiley face) was added in build 9879 of the aforementioned operating system.

Within pre-release Windows builds
The first known screenshots of IE11 came from Windows 8.1 build 9319. All of the known leaked pre-release builds of Windows 8.1 contain a version of IE11 (although the version in build 9299 still brands itself as Internet Explorer 10).

Developer Preview
On 25 July 2013, Microsoft released a build of IE11 known as the "Developer Preview" (build 11.0.9431.0) for Windows 7 and Windows Server 2008 R2. It is available in fourteen languages (Arabic, Catalan, German, English, Spanish, French, Japanese, Korean, Brazilian Portuguese, Russian, Swedish, Turkish, Simplified Chinese and Traditional Chinese) and was compiled for both the x86 and x64 architectures.

Post-release
While focusing on Edge, Microsoft has not given many new features to Internet Explorer in later versions of Windows 10, meaning that IE would eventually become deprecated. Since Windows 10 version 20H2, the About box included in IE11 has been replced with the generic Windows about dialog.

End of support
Microsoft will discontinue support for Internet Explorer 11 on 15 June 2022. However, this only affects Windows 10 and Windows Server (Semi-annual Channel). On Windows 7 (ESU), 8.1, Windows 10 Enterprise LTSC and Windows Server (LTSC), it depends on the support lifecycle of the affected OS.
