RpcSs na plumbing. To disable am no be privacy tweak. Na crash e go cause.

RPC na how plenty part of Windows dey call across processes. Di service name RpcSs na di Service Control Manager entry. Remote Desktop na different stack.

- **Important?**: Critical

  **Na Remote Desktop?**: No

  **E safe to disable?**: No

Feex tok say

If any list tell you make you disable Remote Procedure Call for security, I go close dat list. For Windows, dat service na how di OS dey talk to imself.

## Wetin dis service dey do?

Display name: Remote Procedure Call (RPC). Service name: RpcSs.

RpcSs dey run di RPC endpoint mapper and di RPCSS COM service. Oda services depend on am. E no dey open Remote Desktop listen port by imself.

## History on Windows

Still present

RPC don be core part of Windows NT since di first NT release. Di RpcSs service na di long-standing Service Control Manager name for di RPC subsystem. Dem still require am for Windows 10 and Windows 11. Dis no be di same thing as Remote Desktop Services role.

| RPC for Windows NT | Windows NT 3.1 era (1993)                |
| ------------------ | ---------------------------------------- |
| Service name RpcSs | Long-standing NT SCM name                |
| Still present      | Yes, including Windows 10 and Windows 11 |
| Discontinued       | No                                       |

## Why Windows need am?

COM activation, long list of Windows services, and di Service Control Manager imself dey expect RPC. Supported desktop Windows no dey without am.

## When e dey run?

Always, as long as Windows dey run.

## E suppose dey run always?

Automatic and running. Windows dey treat stop as critical failure.

## I fit disable am?

No

No disable RpcSs. Windows go fail to start oda services and e fit no dey usable again. Restrict Remote Desktop or firewall rules if remote access na wetin you dey fear.

## Wetin go happen if I disable am?

Dependent services go fail. Di machine fit no reach usable desktop. To recover usually mean last known good or repair.

## Process host

RpcSs dey run for dedicated svchost group. No stop random svchost.exe rows to "stop RPC". Check svchost.exe.

## Dependencies

| Depend on | DCOM Server Process Launcher and RPC Endpoint Mapper parts of di same stack |
| --------- | --------------------------------------------------------------------------- |
| Used by   | Most Windows services                                                       |

## Resource behavior

- **CPU**: Low

  **Memory**: Small

  **Network**: Local RPC no be di same thing as to expose RDP

  **Disk**: Low

## Common wahala dem

### Debloat lists dey disable RpcSs

Dem list dey confuse di display name wit Remote Desktop. No follow dem.

### RPC errors after repair

Broken RPC stack need OS repair, no be exe wey you dey download.

## How to troubleshoot

Safe steps first.

### Confirm say di service dey Running

services.msc > Remote Procedure Call (RPC). Startup type suppose be Automatic.

### If wetin you dey fear na Remote Desktop, change dem settings instead

System Properties > Remote, and di firewall. Leave RpcSs on.
