This policy setting allows the configuration of wireless settings using Windows Connect Now (WCN). The WCN Registrar enables the discovery and configuration of devices over Ethernet (UPnP), over In-band 802.11 Wi-Fi, through the Windows Portable Device API (WPD), and via USB Flash drives. Additional options are available to allow discovery and configuration over a specific medium. If this policy setting is enabled, additional choices are available to turn off the operations over a specific medium. If this policy setting is disabled, operations are disabled over all media. If this policy setting is not configured, operations are enabled over all media. The default for this policy setting allows operations over all media.
