Launching Modern IE Window?

I know you can launch IE with

start iexplore URL

…but it always launches in the Desktop browser. Anyone know how I can cause it to launch in the full-screen IE app for Windows 8.1?

My IE always opens on the desktop. Two options for full screen.

[li]Use the command-line switch to open in kiosk mode: iexplore.exe -k ~URL~[/li]
[li]Use the COM object to manipulate the browser (this will give you much more control)

$ie = New-Object -ComObject InternetExplorer.Application
$ie.Visible = $true
$ie.FullScreen = $true
#You can also check out TheatreMode

When I say “full-screen IE” I’m referring to the modern UI version of IE that comes with Windows 8 and above.
