Release Notes
Windows 10 update history

 

[Corrine]

Microsoft has released a cumulative update with non-security improvements and fixes for Windows 10 version 1809. This update includes quality improvements with no new operating system features introduced.

The update is available from Windows Update or the Microsoft Update Catalog. See KB4476976 improvements and fixes.

Note:
Microsoft strongly recommends you install the latest servicing stack update (SSU) for your operating system before installing the latest cumulative update (LCU). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU. If you are using Windows Update, the latest SSU (KB4470788) will be offered to you automatically. To get the stand-alone package for the latest SSU, go to the Microsoft Update Catalog.
