Default Behavior

Windows Audio is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the Windows Audio service is running as NT AUTHORITY\LocalService in its own process of svchost.exe. If Windows Audio fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the Audiosrv service has failed to start due to the error.

Before you begin doing this, make sure that all the services on which Windows Audio depends are configured by default and function properly. See the list of dependencies above.

2. Copy the commands below, paste them into the command window and press ENTER:
