Windows 7 supports TLS 1.1 and TLS 1.2. However these protocol versions are not enabled on Windows 7 by default. On Windows 8 and higher these protocols are enabled by default. To enable TLS 1.1. and TLS 1.2 on Windows 7 please download the below file and double click (import) the Enable TLS 1.x on Windows 7.reg file. If you are not familiar with this rather ask an IT Tech to do this for you.
This update is mostly for users who cant enable SSL/TLS in Outlook or other email programs in Windows 7.
