The May 2019 Patch Tuesday edition is here and brought a new cumulative update (KB4499179 ) to Windows 10 v1709 users. Windows 10 cumulative update KB4499179 bumps the existing version to build number 16299.1146.

This patch came with numerous security updates and fixes to address some new security flaws.

Microsoft no longer releases security patches to Windows 10 version 1709. The tech giant ended official support for Windows 10 v1709 IoT Core, Workstation, Home and Pro versions in April.

Enterprise, loT, and Education edition users still enjoy updates for an extended period of 12 months. 

It is therefore recommended that users upgrade their PCs ASAP. That is the only way users can continue to receive the latest security and feature updates on their machines.
