Finally 😂

It's still there: make a .hta file and double click it. The window you will see is rendered using IE 7.

@darksideplease Ah I have Firefox as my main, no worries there. Thank ya though

No, that is not what i meant. This is a special type of application (HTML Application=HTA) which gets only rendered using a IE 7 engine which is deep down somewhere in system32. You cannot "change" which engine gets used for it, because it's not a website, it's a part program ;)

@darksideplease Oh, my bad haha. I'm not experienced when it comes to things like that.

I know C#'s WebBrowser uses a smaller version of IE - I wonder where that program/part of the program is...

@Lel00 wpf uses IE for browser control true, but UWPs now use Edge's engine.
