I need to restrict access to wireless access points so that users shouldn't be able to connect to wireless ad-hoc network. I also want to disable auto-connecting to unknown, unsecured networks. I figured out , that in "properties" of my wireless card, after clicking "Advanced" in "Wireless networks" tab, I can disable these options, but I need a way to do this automatically via registry/group policy editor. How can I do this?
