Q: How can I prevent users from reconfiguring the wireless options on their device? They're all using Windows 7.
A: You're in luck. Windows 7 exposes extensive wireless configuration options through Group Policy. They're available in the policy engine in a few places. The primary location is in the Wireless Network (IEEE 802.11) Policies section in the Security Settings container. Other policy options, such as Windows Firewall, also change how wireless networking works.
