Yeah, but sadly it's required by the components I use that this is done in specifically this way and every applications that uses these components does it this way. Which includes at least several applications I'm quite sure you already have installed on your PC. And I guarantee to you that you've gave every one of those apps permission to do it without even batting an eye at it.
As far as I've looked into it, there's no work around for this so I'd need to swap to a different HTML engine entirely and I'm not interested in spending the time on it right now.
If you don't want to install it because it looks sketchy to you... just don't run it. That's really it.
(As a side note, the installer currently does only one thing and that's set an elevated FEATURE_BROWSER_EMULATION flag for the game engine.)
I have no idea what makes it being a CMD or not has anything to do with anything. It's a high level C# assembly either way.
