Highly skilled techies in your office, then?
On topic, it must have a development name just as the javascript engine is called "Trident".
Personally, I'm wondering how long it'll last anyway, given the way things seem to be going. I mean, think about it - if Cortana works on Win9 desktops the same way it works on WP then most "applications" end up being an on-demand extension of the assistant. If you wanted to look something up, it'd be more likely to open a wikipedia app for you than en.wikipedia.org in IE. List of search items? They might be _powered_ by Bing but they'll show up in a Cortana return area (or on Windows, presumably sidebar).
It'll probably start eating up functionality that used to be confined to the Start menu, such as last 6 documents/whatever you worked on and THAT in turn means you no longer care about the application that opens your document, just about your document.
I guess what I'm getting at is that for a lot of people, the days of "Computer, do {instruction}" are almost upon us (and typing it in busy offices counts). So much so that it seems to me that individual applications are going to fade into the background. Especially browsers.
