Default Behavior

Peer Networking Grouping is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Peer Networking Grouping service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe along with other services. If Peer Networking Grouping fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the p2psvc service has failed to start due to the error.
