Remote Procedure Call (RPC) (RpcSs) Service Defaults in Windows 7
The RPCSS service is the Service Control Manager for COM and DCOM servers. It performs object activations requests, object exporter resolutions and distributed garbage collection for COM and DCOM servers. If this service is stopped or disabled, programs using COM or DCOM will not function properly. It is strongly recommended that you have the RPCSS service running.

Default Behavior
Remote Procedure Call (RPC) is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the Remote Procedure Call (RPC) service is running as NT AUTHORITY\NetworkService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Remote Procedure Call (RPC) fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the RpcSs service is not running because of the error.
