Microsoft ended support for Windows 10 version 1703 Home/Pro on October 9, 2018
and ends for Windows 10 version 1703 Enterprise/Educational on October 8, 2019.

Lack of support implies that no new security patches for the product
will be released by the vendor. As a result, it is likely to contain
security vulnerabilities. Furthermore, Microsoft is unlikely to
investigate or acknowledge reports of vulnerabilities.");
