Microsoft is warning admins to move PCs from Windows 10 version 1703 for Enterprise and Education to a newer, supported version of the operating system.
There is no extended support available for any edition of Windows 10, version 1703 and will no longer be supported after October 9, 2019. That means no more monthly security updates containing patches for the latest security threats.
[Windows Release Health Update - New Messages] There are new messages about Windows 10, version 1703 end of life and SHA-2 code signing support guidance for Windows 7 SP1 and Windows Server 2008 RS2 SP1. More details here: https://t.co/XpSuHwmrCQ.

To continue receiving security updates, Microsoft recommends that you update your devices to the latest version of Windows 10. For more information on end of service dates and currently supported versions of Windows 10, see the Windows Lifecycle Fact Sheet.
While Windows 10 comes with a hard deadline, Microsoft is offering Windows 7 patches to enterprise customers still running Windows 7 after it reaches EOL on January 14, 2020. Top-tier enterprise Windows 10 customers can get Windows 7 patches at no extra cost for one year.
