Move the Start screen (Metro) to another monitor
If you have a dual monitor setup you might want to move the Start Menu (Metro) open on the second screen.
To achieve this you should open any of the Metro apps including the Desktop and then position your mouse on the top of the opened application. Once cursor turns to hand, click and drag the application to another monitor.
The next time you click on the Win Key on the keyboard again, Start menu will appear on the second monitor.
You can also just use the Keyboard Shortcuts keys to achieve this:
Windows + PageUp – Moves the Start Screen to left monitor
Windows + PageDown – Moves the Start Screen to right monitor
