Oh is that the final name WinRT UI, Metro was such a cooler name.
Well, I still think we should be able to Windows the WinRT UI, and open multiple instances of it. So you can run as many WinRT apps as you need on desktop. Having WinRT apps and then Win 8 apps on the same freaking PC is simply WTF ? I mean two different IE ?
Officially it is Windows 8-style UI apparently, but I don't like that name much, and on the Desktop it's confusing for making a distinction ...
Actually it's called "Modern UI"
