Just an FYI, Windows 10 is only protected from WannaCry if you're fully updated. In my case, I had the updates disabled because of my 0.8mbps connection, and didn't get the security fix.
Correct, however the patch was introduced in windows 10 before Wannacry was even released.
My post is more referring to Versions which had no protection until just under a week ago.
I'll add a note anyway after my mention of windows 10.
