You misunderstood what I wrote. if a program has html instead of it's own actual executable code to render the graphical user interface, EDGE will render it for the program, without identifying itself as edge. It won't look like a web browser to you at all. It'll look like the programs authors intended for their GUI to look, instead.
Windows 10, despite your efforts to 'disable' it also uses Edge to render some of the screens you see when you actually use the OS itself. It's one of the reasons you can't actually remove it. Windows
10 itself, uses it. You can elect not to surf the web with it, but, you can't really stop Windows 10 and some apps from using it to render their own GUIs.Just like win9x, etc etc etc used IE to render some of it's own screens, without appearing to look anything like IE while doing so.
Am I explaining what I meant better?
Although my post can certainly seem that way, I'm not actually being arrogant in it. I was trying to explain something in a way which clearly didn't make sense to you. For that, I do apologize.
