Description
Enables network prediction and prevents users from changing this setting. This controls DNS prefetching, TCP and SSL pre-connection, and pre-rendering of web pages. If this policy is not configured, network prediction is enabled but the user can change it. Policy options mapping: - NetworkPredictionAlways (0) = Predict network actions on any network connection. - NetworkPredictionWifiOnly (1) = Not supported; if this value is used it will be treated as if "Predict network actions on any network connection" (0) was set. - NetworkPredictionNever (2) = Do not predict network actions on any network connection.
