"Our application makes use of legacy IE components." IE on Edge is broken after uninstalling IE in Windows Server 2022, 2019 and Windows 10 and 11

Question

Our application makes use of the below legacy IE components.

1. Invoking through ActiveX
2. window. open call to navigate the external page.

We have enabled IE in edge mode, and it is working as expected. We did not find any issues. We have tested our application using Windows Server 2016, 2019, and 2022, Windows 10 and 11 machines.

But, when we uninstall IE through optional features, it breaks IE in Edge mode. So, After manually uninstalling IE, We are not able to launch the application because it asks us to install Internet Explorer.

We uninstall IE manually because, according to a June 13 Microsoft announcement, IE will be uninstalled as part of a security patch upgrade.So, we have experimented.

Questions:

1. For IE in Edge mode, do we really require Iexplore.exe to have physical reference in the machine?
2. Is there a way to avoid automatic uninstalling IE through the June 13, 2023 security patch upgrade?
3. What is the recommendation for the "window.open scenario?

Thanks,
