This policy applies to Wireless Display connections. This policy means that the use of a PIN for pairing to Wireless Display devices is required rather than optional. Conversely it means that Push Button is NOT allowed. If this policy setting is disabled or is not configured, by default Push Button pairing is allowed (but not necessarily preferred). Counter Measure: Configure this setting depending on your organization's requirements. Potential Impact: Users are unable to use Push Button pairing. Fix: (1) GPO: Computer Configuration\Administrative Templates\Network\Wireless Display\Require PIN pairing (2) REG: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WirelessDisplay!EnforcePinBasedPairing
