kyleparliament1 Hi! If you need to utilize Microsoft Edge IE mode for your legacy sites, the IE11 engine is required.

 

Instead of removing IE11 it is possible to disable IE11 as a standalone browser and IE mode will continue to function.  Here is additional documentation about disabling IE11: Disable Internet Explorer 11 | Microsoft Docs

 

In regard to your other question, below is a section copied from Internet Explorer 11 desktop app retirement FAQ - Microsoft Tech Community

 

Will the Internet Explorer 11 desktop application be removed from devices?

No. The IE11 desktop application will not be removed from devices, as the IE11 engine is required for IE mode to function. However, after the IE11 desktop application is retired on June 15, 2022, it will be disabled permanently. 

 

Will iexplore.exe be removed from devices?

No, but if a user tries to access it, they will be unable to open IE11 and will be redirected to Microsoft Edge.

 

Thanks!
