[WIN7] Blocking access to Network Applet via Wireless systray

I need to block all access by users to the network control panel applet. I figured out that using the local GPO I can block access to the Control panel and/or only display certain items. HOWEVER, when I click on the wireless systray application and click on Open Network and Sharing Center, it does!, despite the control panel being blocked. I know I can extend the AD schema and make the policy changes that way, but that involves a bureaucratic mess that I don't want to get into. Any other suggestions? -- Every government has its Secret Service branch: America, CIA; France, Deuxieme Bureau; England, MI5. NATO also has its own.
