I'm trying to open the Metro version of Internet Explorer, however it opens as a desktop app. It just goes from the metro interface to the desktop. How can I do this?
Press + R and type
Navigate the tree to the area depicted in the screenshot.
Now, double click on "Set how links are opened in Internet Explorer" and change it accordingly. Read the help text to understand what it does. The option immediately below it, "Open Internet Explorer tiles on the desktop", may also be helpful.
Note that in the second screenshot, the option "Always in Internet Explorer on the desktop", is exactly the opposite of what you want, so you need to change it to "Always in Internet Explorer" to always use the ---Metro--- Modern version of IE.
