Devices using a manual or auto-configured proxy, especially with a virtual private network (VPN), might show limited or no internet connection status in the Network Connectivity Status Indicator (NCSI) in the notification area. This might happen when connected to or disconnected from a VPN or after changing the state between the two.

How to get this update

Before installing this update
