Here's the complete process I followed:

1. Search for "windows smb server vuln" in Google.

2. "Microsoft Security Bulletin MS17-010 - Critical"[0] is the link I'm looking for.

3. Search for your version in the list. Mine is "Windows 10 Version 1607", listed in the table with 4013429 (right next to the Windows version, not in "Updates replaced"). That's my update number.

I think a lot of the confusion here is what constitutes a "version" of windows 10.

Indeed. As far as I can tell they are like what used to be Service Packs?

E.g.: I didn't install the so-called Creators Update so I'm not in the latest Windows 10 version.

I'm no Windows sysadmin though so I'm not really sure.
