This is another group policy setting. You can hide the control panel component.
first, open the group policy, this time we can use the command prompt, just type gpedit.msc.
now go to USER CONFIGURATION > ADMINISTRATIVE TEMPLATES > CONTROL PANEL.
here You’ll find hide specified control panel applets.
now double click it and click ADD button, and add what component of the control panel you want to hide.
you can input it’s name like what it displayed in control panel window or it’s cpl file (you can find the cpl file in %systemroot%system32).
Now that sure hide it from control panel, but beware they can still execute the cpl file directly, so to prevent this you need to move the corresponded file to somewhere else.
