Internet Explorer 11 (IE11) is the eleventh and final version of the Internet Explorer web browser, by now retired. It was initially included in the release of Windows 8.1, Windows RT 8.1 and Windows Server 2012 R2 on October 17, 2013, and was later released for Windows 7 and Windows Server 2008 R2 on November 7, 2013. It is the successor to Internet Explorer 10, released the previous year, and was the original, default browser in Windows 8.1 and Windows Server 2012 R2. Internet Explorer 11 was also included in the release of Windows 10 on July 29, 2015, as well as in Windows Server 2016 and Windows Server 2019. On April 16, 2019, Internet Explorer 11 was made available to Windows Server 2012 and Windows Embedded 8 Standard as the final expansion of Internet Explorer 11 availability.{{cite web|url=https://techcommunity.microsoft.com/t5/windows-embedded-blog/ie11-coming-to-windows-embedded-8-standard/ba-p/326747|title=IE11 coming to Windows Embedded 8 Standard!|date=2019-01-28|access-date=2022-09-23|publisher=Microsoft|archive-url=https://web.archive.org/web/20220923144220/https://techcommunity.microsoft.com/t5/windows-embedded-blog/ie11-coming-to-windows-embedded-8-standard/ba-p/326747|archive-date=2022-09-23|url-status=live}}{{Cite web|url=https://www.zdnet.com/article/microsoft-makes-final-push-to-rid-world-of-internet-explorer-10/|title=Microsoft makes final push to rid world of Internet Explorer 10|last=Tung|first=Liam|website=ZDNet|language=en|access-date=2019-03-13}} Internet Explorer 11, like its predecessor, is not available for Windows 8, Windows Vista, Windows Server 2008, and earlier versions of Windows and Windows Server.

Microsoft adjusted their product lifecycle policies to only support the most recent version of Internet Explorer offered for any given version of Windows on January 12, 2016,{{cite web |url=https://www.microsoft.com/en-us/WindowsForBusiness/End-of-IE-support |title=Support for older versions of Internet Explorer ends on January 12, 2016 |website=Microsoft |access-date=June 13, 2022 |archive-url=https://web.archive.org/web/20160109124653/https://www.microsoft.com/en-us/WindowsForBusiness/End-of-IE-support |archive-date=January 9, 2016 |url-status=dead}} and later expanded to Windows Server 2012 and Windows Embedded 8 Standard on January 31, 2020.{{cite web |url=https://web.archive.org/web/20200812121833/https://mcpmag.com/articles/2019/01/30/ie-10-support-cliff-in-2020.aspx |title=Microsoft Warns of IE 10 Support Cliff in 2020 |website=Certified Professional Magazine |publisher=Microsoft |accessdate=January 12, 2024 |archive-url=https://mcpmag.com/articles/2019/01/30/ie-10-support-cliff-in-2020.aspx |archive-date=August 12, 2020 |url-status=live}} Support for Internet Explorer 11, now regarded as an "OS component", is bound to the version of the Windows it is installed on. Thus, Microsoft provides updates only to currently supported versions of Windows. This includes Windows 10 LTSC (formerly LTSB), and supported Windows Server versions, which will continue to receive IE11 updates until their respective end-of-support dates. The exception to this is the Windows 10 Semi-Annual Channel (SAC). For SAC versions of Windows 10, Internet Explorer 11 support ended on June 15, 2022, and it was permanently disabled on February 14, 2023. Any remaining icons or shortcuts were due to be removed on June 13, 2023, however, on May 19, 2023, various organizations disapproved, leading Microsoft to withdraw the change.{{cite web |url=https://docs.microsoft.com/en-us/lifecycle/faq/internet-explorer-microsoft-edge |title=Lifecycle FAQ - Internet Explorer and Microsoft Edge |date=2021-11-03 |access-date=2022-06-13 |archive-url=https://web.archive.org/web/20220613224114/https://docs.microsoft.com/en-us/lifecycle/faq/internet-explorer-microsoft-edge |archive-date=2022-06-13 |url-status=live}}{{cite web |url=https://techcommunity.microsoft.com/t5/windows-it-pro-blog/internet-explorer-11-desktop-app-retirement-faq/ba-p/2366549 |title=Internet Explorer 11 desktop app retirement FAQ |date=2022-06-13 |access-date=2022-06-13 |publisher=Microsoft |archive-url=https://web.archive.org/web/20220613223618/https://techcommunity.microsoft.com/t5/windows-it-pro-blog/internet-explorer-11-desktop-app-retirement-faq/ba-p/2366549 |archive-date=2022-06-13 |url-status=live}} Furthermore, despite Microsoft's alleged permanent IE11 disablement, IE11 can still be accessed in some capacity using unofficial methods.{{Cite news |last=Tkachenko |first=Sergey |date=2022-08-04 |title=How to launch Internet Explorer on Windows 11 if you really need it |url=https://winaero.com/how-to-launch-internet-explorer-on-windows-11-if-you-really-need-it/ |url-status=live |archive-url=http://web.archive.org/web/20240919032050/https://winaero.com/how-to-launch-internet-explorer-on-windows-11-if-you-really-need-it/ |archive-date=2024-09-19 |access-date=2025-01-20 |work=Winaero |language=en-US}}

IE Mode, a feature of Microsoft Edge, enables Edge to display web pages using Internet Explorer 11's Trident layout engine and other core components.{{cite web |url=https://docs.microsoft.com/en-us/deployedge/edge-ie-mode |title=What is Internet Explorer (IE) mode? |date=2022-03-02 |access-date=2022-06-13 |archive-url=https://web.archive.org/web/20220613233617/https://docs.microsoft.com/en-us/deployedge/edge-ie-mode |archive-date=2022-06-13 |url-status=live}} Through IE Mode, the underlying technology of Internet Explorer 11 partially exists on Windows that do not support Internet Explorer as a proper application, such as Windows 11 and later versions that derive from the Windows 11 codebase.{{cite web|url=https://www.theverge.com/2021/6/25/22550714/microsoft-windows-11-internet-explorer-disabled|title=Windows 11 is deleting Internet Explorer|author=Tom Warren|website=The Verge|date=2021-06-25|access-date=2021-08-12}} Microsoft has announced support for IE Mode through at least 2029, with a one-year advance notice prior to retiring this variant of IE11.

Internet Explorer 11 is already retired and out of support (i.e. most often the desktop browser was disabled and Edge took its place), for e.g. Home and Pro (with some paid ESU exception to 2028{{Cite web|url=https://learn.microsoft.com/en-us/lifecycle/faq/extended-security-updates|title=Product Lifecycle FAQ - Extended Security Updates|website=learn.microsoft.com}}), with some exceptions such as for the Windows 10 China Government Edition,{{Cite news |title=Internet Explorer 11 desktop app retirement FAQ {{!}} Microsoft Community Hub |url=https://techcommunity.microsoft.com/blog/windows-itpro-blog/internet-explorer-11-desktop-app-retirement-faq/2366549 |archive-url=http://web.archive.org/web/20250123184955/https://techcommunity.microsoft.com/blog/windows-itpro-blog/internet-explorer-11-desktop-app-retirement-faq/2366549 |archive-date=2025-01-23 |access-date=2025-01-24 |work=TECHCOMMUNITY.MICROSOFT.COM |language=en-US}} and the Internet Explorer mode in Microsoft Edge remains, so in that sense the core of IE 11 (its rendering engine) remains supported.{{Cite web |title=Lifecycle FAQ - Windows |url=https://learn.microsoft.com/en-us/lifecycle/faq/windows |access-date=2025-01-24 |website=learn.microsoft.com |language=en-us}} Windows 10 IoT Enterprise LTSC 2021 (for specialized devices – for example, those that control medical equipment or automated teller machines) has end of support on January 13, 2032, and with it support for Internet Explorer 11 fully ends (if not sooner in 2029 as explained above).

Performance

In a November 2013 review by SitePoint, IE11 scored better than Google Chrome 30 and Firefox 26 in WebKit's SunSpider test and Google's WebGL test. It tied with Chrome for fastest in Microsoft's "fish aquarium" benchmark for WebGL and came last in Google's V8 performance benchmark. As a result of the speed improvements, the reviewer said "if you switched to Chrome for speed alone, you're now using the wrong browser." IE11 was also observed to use less memory with multiple tabs open than contemporary versions of Chrome and Firefox.

In August 2015, SitePoint again benchmarked IE11 in its review for Microsoft Edge [Legacy], where Edge 12, Chrome 44 and Firefox 39 were also present. IE11 came last in Apple's JetStream test (which replaced SunSpider) and Google's Octane test (which replaces V8) but it came second in Microsoft's "fish aquarium" test, after Edge.{{cite web|last1=Buckler|first1=Craig|title=Microsoft Edge: the Review|url=https://www.sitepoint.com/microsoft-edge-review/|website=SitePoint|date=August 18, 2015}}
