Note: Windows 7 and Windows 2008 are already EOL. You might want to consider upgrading to latest version.

TLS v1.0 and v1.1 are being deprecated across entire Internet. Win 7/2008 by default have them disabled. In order to continue smooth sailing in Internet waters, you might want to follow MS advice on enabling TLS v1.2.

For that, you will need to:

1. Install kb3140245 package
2. Run Attached file OR manually populate/update registry values as per article referenced above.
3. You will probably have to reboot the PC.

Test if you've got TLS v1.2 support by opening up SSLLabs Client test page in Internet Explorer or EDGE (not firefox/chrome/whatever).
