This security update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:
- Addressed issue that was preventing the Camera application from saving a captured image when “Show recently opened items in Jump Lists on Start or the taskbar” settings is enabled.
- Improved the Host Network Service (HNS) to support an overlay network driver for use on Windows Server 2016 to connect containers across hosts using Docker Engine in Swarm Mode.
