Yesterday was the third Tuesday of the month and that means, usually, that Microsoft releases another batch of cumulative updates for various versions of Windows 10.

Microsoft released the updates KB4489894, KB4489890, KB4489888 and KB4489889 yesterday for Windows 10 version 1803, 1709, 1703, and 1607 respectively. The update for the current version of Windows 10, Windows 10 version 1809, is delayed as usually.

The updates share most of the improvements and fixes. The updates can be downloaded manually from the Microsoft Update Catalog website or installed by running a manual check for updates. It is recommended to sit them out unless you are affected by the issues that they fix.
