Default Behavior

Peer Networking Identity Manager is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Peer Networking Identity Manager service is started, it runs as NT AUTHORITY\LocalService in a process of svchost.exe, sharing it with other services. If Peer Networking Identity Manager fails to start, the error details are added to Windows 8 error log.
