As part of the TLS handshake with client cert authentication, the client sends a "Certificate Verify" message (

What I have found from capturing packet dumps with Wireshark on multiple machines (Windows 10, Windows 2012 R2) is that the Certificate Verify message is NEVER sent with TLS1.2.

However, if I explicitly set it to TLS1.1 or TLS1.0, the cert verify message is indeed sent and the connection is established.

Therefore, I need to know why this message isn't sent with TLS1.2 (at least on newer versions of Windows) and how can I get it to send that?
