Microsoft recently released the servicing stack update for Windows 10 v1903 update users. Like most servicing stack updates, it is a quality improvement update aiming to fix minor issues. You will find the direct download links for KB4509096 update below.
In case you don't know, servicing stack updates are targeted updates that make changes and improvements to the servicing stack. In general, the servicing stack is responsible for Windows updates. If there is a problem or reliability issue with the servicing stack, that reflects in the Windows update and may cause the system to not download the updates properly.
