Windows 10 version 1903 users continue to suffer from issues after installing cumulative updates. The latest one, KB4515384, adds a number of new bugs to the OS, including broken network connectivity, issues with mutli-channel audio, and even more.
KB4515384 was released for Windows 10 version 1903 on September 10, 2019, raising the OS build number to 18362.356. It is a cumulative update that is intended to improve reliability and performance of the operating system. Unfortunately, the annoying search bug retains in this release. Also, there are a number of new issues in this update.
In games that are able to produce multi-channel audio, such as Apex Legends, Overwatch, PlayerUnknown's Battlegrounds, World of Warcraft Classic, and others, KB4515384 may cause missing audio effects and a low level of sound volume. Microsoft is aware about this issue, and recommends the following to mitigate it.
To mitigate the issue, open settings in the impacted game and disable multi-channel audio, if this option is available. You can also search in the Windows Control Panel for third-party audio device control panels and disable Multi-channel audio or Virtual Surround Sound, if these options are available.
We are working on a resolution and estimate a solution will be available in late September.

Some users report that KB4515384 prevents them from opening Action Center, Edge, and certain Store apps. Uninstalling the problematic update resolves this.
