Earlier quoted context omitted.
The comment on randomly opening windows is fair (I don't see what caused it either), but this was a build VM, not a workstation - there is no reason to upgrade the browser. A more pertinent question is why are MS still shipping IE by default.
It was a "build VM" running the client edition of Windows. Do you install Ubuntu Desktop on your build VMs and expect Firefox not to be bundled?
IE was superceded by Edge a long time ago. I'm not arguing for a different choice of browser, I'm arguing for them not to ship deprecated browsers.
