Internet Explorer 11 is the last version of Internet Explorer, which was released on 17 October 2013 and shipped alongside Windows 8.1 and Windows Server 2012 R2. An update was later made available for Windows 7 Service Pack 1 and Windows Server 2008 R2 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,^[1] although it can also be unofficially installed on Windows 8.^[2]

Internet Explorer 11 is also part of Windows 10, Windows Server 2016, Windows Server 2019 and Windows Server 2022, however, it is not set as the default browser (excluding Windows Server 2016 and 2019, in which Microsoft Edge is not available by default) to promote the Microsoft Edge browser. A feedback button (in the form of a smiley face) was added in build 9879 of Windows 10 and build 9926 of Windows Server 2016.

History[edit | edit source]

Within pre-release Windows builds[edit | edit source]

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 (since build 9299) and Windows Server 2012 R2 contain a version of IE11 (although the version in build 9299 still brands itself as Internet Explorer 10).

Developer Preview[edit | edit source]

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 14 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[edit | edit source]

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 October 2020 Update and Windows Server 2022, the About box included in IE11 has been replaced with the generic Windows version dialog.

End of support and removal[edit | edit source]

Microsoft discontinued support for Internet Explorer 11 on 15 June 2022. However, this only affects Windows 10 and Windows Server releases in the Semi-Annual Channel.^[3] On Windows 7 with Extended Security Updates, Windows 8.1, Windows 10 and Windows Server releases in the Long-Term Servicing Channel, it depends on the support lifecycle of the affected OS. Starting with Windows 10 build 21387, IE11 cannot start anymore, unless ieframe.dll is replaced with an older version such as the one from build 21382.1000. Attempting to start iexplore.exe will start Edge instead. In Windows 10 build 19044.1499, a reminder dialog box was added to IE11 that warns users that support for the application would end on 15 June 2022.

After the EOL date, Microsoft started redirecting users to Microsoft Edge through a pop-up message that appears when users try to launch IE11 and offers to automatically move browsing data from IE11 to Microsoft Edge.^[3]

In October 2022, Microsoft announced that IE11 will be completely disabled on certain versions of Windows 10 starting with the February 2023 security update via Windows Update.^[3]
