There might be a way to it with AutoHotKey, but I'd prefer a way that will actually change the key's function, instead of tricking it using software... if that makes any sense...
I know that if you hold PN+ windows, it will activatate the windows button and open the start menu, but I have yet to be able to do PN+ win+ D... it doesn't work that way I guess....
You could also program PN +D to do Win + D, but I think Win + D and all other Windows functions would be better using the windows key if possible....
I forgot, but there is a way, to use a combination of some other keys to activate capslock.. . so that function won't be lost if we can replace the button's function ...
