Hello,
it seems that if you want to change display settings it is not possible.
To reproduce it, right click on desktop and choose "Display settings": you'll receive the message in a dialog box "You'll need a new app to open this ms-settings"; if you notice, the button with label "OK" is gray so the only thing to do to cancel the dialog is a left click on the desktop.
I attached a screenshot.
Only one notice: the installation is a virtual machine in Hyper-V (on Windows 10 build 10240).
