Hi
First of all, there is no standard way of creating a Desktop shortcut for an app, it differs depending on the menu style you that you are using.
When you right click on app you get the "More" submenu, which also differs in content, depending on which menu style you are using, it should be standard throughout the different menu styles. It also differs depending on whether you press the Start Button on your keyboard or whether you click on the Start 11 Icon. Every time the 'More' submenu is given as an option it should include a "Create Shortcut on Desktop" option, sometimes it does and other times it doesn't, and this is my main point.
I personally do not pin all my apps to the start11 menu because it gets too long.
Kind Regards
