Remote Procedure Call (RPC)

General Information

This service is rather vital. Practically everything depends on this service to be running. This is also one of the few services that you cannot disable via the Services MMC, nor can you change the state with a registry patch.

Windows 8

Default Description

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.

Additional Information

This service is rather vital. Practically everything depends on this service to be running. This is also one of the only services that you cannot disable via the Services MMC. Previously, if you disabled this service in Windows 2000, your computer would become unbootable. What I am trying to tell you is leave this service on Automatic and absolutely do not disable it.
