Je crois that Run5K was asking about "taskbar" raccourcis, not "systray" icônes which, as you said ne sont pas raccourcis, rather elements that can be désactivé/activé depuis le location you specified.
The location du taskbar icônes is the same in Windows 10 as it is in Windows 7 (and I would presume is the same for Windows 8/8.1 également, though Je n'ai pas tested):
