Default Behavior

Application Identity is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Application Identity service is started, it runs as NT Authority\LocalService in a process of svchost.exe, sharing it with other services. If Application Identity fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the AppIDSvc service hasn't been started.


Application Identity can't start, if any service from the list below is disabled or not available:
