Question

I want to more space for my game application. If I will use the system tray space for application, Microsoft requires any setting for system tray for user otherwise any problem happend for microsfot certification.

Answer 1

There are no certification requirements around the system tray’s visibility, as far as I am aware. The APIs provide the means to hide the tray as follows…

Silverlight

In the page declaration for any page you want to hide the system tray, add the following.

shell:SystemTray.IsVisible="False" 

XNA

In the constructor for the pages where you want to hide the system tray, find the line

graphics = new GraphicsDeviceManager(this);  

and after it, add the following

graphics.IsFullScreen = true;
