And the vast majority of the webviews used by the OS were IE (now webview2, based on Edge instead).
It turns out the ability to display a webpage is a pretty critical part of any modern operating system - they all support some form of a webview. The one in Windows is based on browsers that MS develops and owns (IE, then EdgeClassic, now Chromium Edge). It's absolutely baked in still.
> Microsoft Edge is the web browser recommended by Microsoft and is the default web browser for Windows. Because Windows supports applications that rely on the web platform, our default web browser is an essential component of our operating system and can’t be uninstalled. To provide our users with compatibility, compliance, accessibility, and performance, we'll continue updating Microsoft Edge through the browser installer or Windows updates.

I still click on links in some parts of the OS or other applications on Windows 10 that opens in Microsoft Edge, even though I've set Firefox to be my default browser.
I don't know if it shares with the core that buildin edge use. But if it is the case, then obviously you can't remove it just like you can't remove core of ie in pre windows 11 world.
By the way, some function of the new shell seems relies on service not available under safe mode. So the explore.exe will crash repeatedly when you are in safe mode. __And it openes the edge for help article every time it crashed__, so you ends up with dozens of same tab in the edge.
