Microsoft has released a so-called preview update for the 2019 versions of Windows 10 . The update is offered to users as an optional update and, as far as is known, fixes problems with Edge, with audio in games and with USB 3.0 hubs.
While Microsoft did not publish a preview for the newer Windows 10 versions 2004 and 20H2 after the patch day, but an unscheduled update, the Windows versions 1903 and 1909 get the classic preview updates. The Windows team has now released the build with the number 18362.1237 for Windows 10 version 1903 and 18363.1237 for 1909 and entered the update in the Knowledge Base under KB4586819 .
The update is cumulative and optional, i.e. it replaces previous updates and has no security-relevant changes that make an update an urgent recommendation.
Use the Windows update function
The update brings a number of bug
fixes. Microsoft is now distributing the new cumulative update via Windows
Update and is also making it available in the Microsoft Update Catalog. With
the new preview Microsoft addresses all Windows 10 version 1903 and 1909
editions as well as Windows Server version 1903 and 1909.
