Windows Audio Endpoint Builder Service is missing?
It appears that the Windows Audio Endpoint Builder service goes missing in the Services MMC (
services.msc) on some systems for unknown reasons. The user may have inadvertently deleted the service. As a result, the Windows Audio service wouldn’t start.
To resolve the issue, reinstate the Windows Audio Endpoint Builder service on Windows 10 using the following registry fix:
