Full support for Internet Explorer (IE) version 11 was discontinued on which date, with the alternative being Microsoft Edge's IE compatibility mode for legacy sites that require it?

Full support for Internet Explorer 11 ended on 15 June 2022, after which Microsoft Edge's IE mode covers legacy sites.

The date 15 June 2021 is a year too early for the retirement.

25 June 2022 is close but is not the actual retirement date.

25 June 2021 does not match the end of IE 11 support.

Microsoft Edge includes an IE compatibility mode so old sites still work.

Internet Explorer had been Microsoft's default browser for decades before Edge replaced it.
