How can I block in Control Panel the option "Change Adapter Settings"

How can I block/disable in Control Panel option ChangeAdapterSettings

I need to block/hide/disable in the control panel the option "Change Adapter Settings". I have a DHCP server and I dont want my users configure a network adapter with a fixed ip.

I am looking for registry section or a directive that makes the trick.

Thanks in advance.

Tweak Winsecret

I found this software, but I wonder how it is made the trick.

I need to apply "it" throw an in-house application.
