If Micrsoft didn't mess up badly with Windows 10...
... probably it would have been much more widespread.
Anyway, despite Microsoft PR BS, Windows 10 is vulnerable to ETHERNALBLUE just like 7 if not patched (see https://technet.microsoft.com/en-us/library/security/ms17-010.aspx, it's CVE-2017-0144). The only difference is the forced patching of Win10 could have lead to less vulnerable systems - but in a WSUS system patches needs to be approved anyway.
