Turn Off Ability To Configure Using A USB Flash Drive setting:
Prevents Windows from being able to store a Windows Connect Now configuration to a
UFD. Because the Windows Connect Now information stored on a UFD contains information
that can allow computers to access your protected wireless network, you might choose to
disable this setting to improve the security of your wireless networks.
