Default Behavior

Web Account Manager is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Web Account Manager service is started, it is running as LocalSystem in a shared process of svchost.exe along with other services. If Web Account Manager fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the TokenBroker service has failed to start due to the error.


Web Account Manager cannot be started under any conditions, if the User Manager service is disabled.
