How to do so that OS does not recognize teensy as teensy device

[well]

So, I am working on a project to use teensy as a keyboard/mouse..

Issue is that I want OS to recognize teensy only as USB HID compatible keyboard/mouse, without any COM4 ports showing up in device manager..

Is that possible? And how if it is?

In Arduino, use the Tools > USB Type menu (to choose something other than Serial). Then Upload. Yes, really, it's that simple.
