I'm using Windows 8 Pro with Internet Explorer 10 on, and I downloaded Google Chrome, setting it the default browser. After that I saw that when I click on the Internet Explorer shortcut on the Start screen it opened me IE10 in the Desktop. Now I want to ask: can I use the IE10 App in Metro Style without making her the default browser?
You can only use one Metro browser at a time, you installed Chrome which took over as the default browser. Microsoft designed it this way on purpose.
