A little bit less than a year ago Microsoft announced that they are going to retire Internet Explorer 11 browser on June 15, 2022. Which is now almost 4 months away. They have also since posted an FAQ detailing all the steps and which versions of Windows can still have IE for some time (LTSC and Server). And explained that IE engine itself is not going away until at least 2029 for supported versions of Windows 10 and 11, it is just the browser itself that is going to be disabled. They also made advancements in Site List for IE mode management and made it possible to do it completely via Microsoft 365 console. IE mode is used in Edge to utilize IE engine to render older websites and systems that still rely on old technology. It is when i remembered about a new group policy they added in January of 2021 that enabled administrators to disable IE11. Which in turn allows to simulate disabling Internet Explorer before its official retirement date.
