[6] Support for Internet Explorer 11, now regarded as an "OS component", is bound to the version of the Windows it is installed on.

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.

[11] Microsoft has announced support for IE Mode through at least 2029, with a one-year advance notice prior to retiring this variant of IE11.

[7] 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[12]), with some exceptions such as for the Windows 10 China Government Edition,[13] and the Internet Explorer mode in Microsoft Edge remains, so in that sense the core of IE 11 (its rendering engine) remains supported.

IE11 features redesigned developer tools,[15] support for WebGL,[16] enhanced scaling for high DPI screens,[17] prerender and prefetch.

[23] The "document mode" feature in the developer toolset (F12) allows simulating the rendering behaviour of Internet Explorer versions 5 to 10 to facilitate testing pages for compatibility.

Internet Explorer is set up to run websites, based on legacy HTML technologies, which are not, or improperly, supported in Microsoft Edge.
