>>What exactly do you mean by compatibility? The webbrowser activeX allows for IE4 to IE11 emulation. I do not know whether it will run when only edge is installed (Edge will support the IE modes as well), but I can't imagine MS would end its support for the webbrower control anytime soon.
>>
>Edge does NOT allow activeX controls and does NOT run BHO if I read descriptions correctly.
That is kind of irrelevant. It is not whether activeX to run into edge, but whether edge runs in an activeX control.
>So IMO it is uncertain if IE11 "stays" installed on W10 after support ends in 2 weeks.
I can guarantee that would not be the case as it would break a lot of applications, including applications from MS themselves.
I think you got the wrong date as well. Its state June 6th 2022. So one more year to go before it is left unsupported. I have no reason to think that this would mean the IE runtimes needed for the webbrowser control will be uninstalled as it clearly still is supported for the other versions of Windows 10.
>WebBrowser is MsHtml.Dll if you look at it as activeX object, so 2nd cited FAQ goes to the heart of WebBrowser similar to IE as in createobject("InternetExplorer.Application"), which I also used sometimes in roboting to better combat memory leaks.

What if my enterprise line-of-business (LOB) application has a dependency on a version of Internet Explorer that reached end of support?
>
>Microsoft is committed to supporting Internet Explorer mode in Microsoft Edge through at least 2029, on supported operating systems. Additionally, Microsoft will provide a minimum of one year notice prior to end of support for IE mode. Windows support dates are documented on the Product Lifecycle page and may require an Extended Security Update (ESU) license, if available, to receive operating system security updates beyond its End of Support date.
>
>What is Microsoft's guidance if customers run an application that depends on specific Internet Explorer runtime DLLs?
>
>Microsoft will release security updates only for the latest version of Internet Explorer for each Windows operating system. Customers must install the latest version of Internet Explorer to update the Internet Explorer runtime DLLs, receive updates, and remain in a supported configuration.
>
>If a customer has turned off the Internet Explorer feature but has third-party software that uses Internet Explorer runtime DLLs, how can the Internet Explorer runtime DLLs be updated?
>
>If customers need an update to the Internet Explorer runtime DLLs, they must install the latest version of Internet Explorer (IE11) to update the runtime DLLs. After doing so they will continue to receive security updates.Would this indicate that de-installing IE would leave the runtime DLLs still in there ?
