There is no notification from Windows when our built-in VPN connection (inside Windows) suddenly disconnects or VPN connections drops.
it poses security risk as well as discomfort and other problems. there is a reason when user uses VPN connection, to stay protected, secure etc.
so when VPN connection suddenly drops or disconnects for any reason, user must be notified.
