Activate TLS protocol in Windows registry

Important: Before you do any change on the Windows registry, it strongly recommended to back it up.

 Right-click Windows button and select Run Type "regedit", and click OK Then go to "Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols", and create one key and two DWORD(32-bit) values, as the image below shows.

Key/Key Values Name Value
key TLS 1.2
DWORD(32-bit) DisabledByDefault 0
DWORD(32-bit) Enabled 1

Now, you can exit the registry and restart your machine.
