Is block-outside-dns required for Windows 10 clients?
--block-outside-dns puts firewall rules in place which deny any DNS queries egress to any network adapter other than the TAP adapter and thereby the VPN. The decision to use it is left to the discretion of the user ..

If the OpenVPN client crashes, is this block then removed again?
How can openvpn remove the block if it has crashed ?
If you can reliably crash openvpn then please submit a bug report.
