I found out why the RST,ACK is not sent in case of Windows 10. Actually irrespective of Windows version, the Firewall status was creating such behaviour.

If the Firewall is Enabled for the network, in cases where the SYN,ACK is received from the server from the port number whose session has closed at client side, the RST,ACK is not sent.

If the Firewall is disabled, the RST,ACK is sent.
