I don't know either, so I asked Larry Osterman, who was in charge of the Volume icon. And he didn't know either. He was merely given new icons by the design team. But that doesn't stop me f...

Shortcut properties are in the shortcut, so if they can read the shortcut, they can read the properties

Raymond Chen

A customer wanted to know if "there was a way to hide the properties of a shortcut." We asked for an explanation of the problem they were trying to solve, so we could understand what their question meant. The customer liaison explained: The customer is insisting on this, even though I think it's really the wrong approach. They want to put a passw...
