Great, windows 10 was updated, and you get this 'Could not create SSL/TLS secure channel' error whenever you try to connect to any older device or service (that you can't update).
Not delving into a rant why mickeysoft is just stupid to do so or the stupidity shown by a lot of so-called "specialists" coming up with godknows what kind of crap, here's a real solution.
Download this security.reg file and execute it. Please do check the content of it before you run anything on your system!!
All this should do: enable all older TLS transport layers.

After you imported this file, you don't even have to reboot, it just works.
