This article will guide you through enabling TLS 1.2 on Windows 7.
TLS is a replacement for 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 email, file transfers, VPN connection, and voice-over IP.
Windows 7 supports TLS 1.1 and TLS 1.2. But these protocol versions are not enabled on Windows 7 by default. However, these protocols are enabled by default on Windows 8 and higher versions.
