Logon: Network selection UI must not be displayed

3476077b-5d03-4819-9ef0-213402f37eed

Enabling interaction with the network selection UI allows users to change connections to available networks without signing into Windows. There are several attacks based on this.

Remediation

To fix this configure the policy value for Computer Configuration >> Administrative Templates >> System >> Logon >> "Do not display network selection UI" to "Enabled".
