How to enable TLS 1.2 in various versions of Windows

Transport Layer Security (TLS) is a replacement of the Secure Sockets Layer protocol (SSL). It provides secure communications on the internet. It is used for web browsers and other applications that require data to be securely exchanged over a network such as an email, file transfers, VPN connection, and voice over IP.

HMRC have stopped supporting older security methods of TLS 1.0 and TLS 1.1 which were built into Microsoft Windows operating systems.
