Remote Procedure Call (RPC) - Windows 7 Service
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.
This service also exists in Windows 10, 11, 8, Vista and XP.
