Update .lnk icon

[_pi]

i have a shortcut on desktop where i change the icon on result of a function.
currently i use CreateShortcutEx for updating the icon, but i would prefer to update the .lnk
without overwriting it.
i use stardock fences to organize my desktop icons in areas, unfortunately it tries to handle
my shortcut because it has been created again.

i would like to change only the icon info and send some kind of refresh to desktop.

thanks
