# mmc.exe

Windows Process: Microsoft Corporation

Also called mmc, microsoft management console, snap-in host

Windows, System Component

Microsoft Management Console. It hosts snap-ins such as services.msc. It is not SystemSettings.exe and not services.exe.

## What you need to know

mmc hosts snap-ins; it is not SystemSettings.exe and not services.exe.

mmc.exe is the console that loads .msc snap-ins. services.msc is a document MMC opens. services.exe is Service Control Manager, always there. SystemSettings.exe is the Settings app. Closing MMC does not stop SCM.

- **Safe?**: Yes, in System32

  **Same as Settings?**: No. Settings is SystemSettings.exe

  **Same as services.exe?**: No. That is Service Control Manager

Feex says

If I opened services.msc, I expect mmc. I do not end services.exe because I closed the snap-in, and I do not hunt Settings for that list.

## What is mmc.exe?

mmc hosts snap-ins; it is not SystemSettings.exe and not services.exe. Opening services.msc launches this host with the Services snap-in. SCM remains services.exe. Settings remains SystemSettings.exe.

## What does it do?

It loads an .msc and the snap-in DLL. It does not replace the Services list in Settings and it does not become Service Control Manager.

## Why is it running?

You opened a snap-in (Services, Event Viewer, Disk Management, Certificates). A copy with no window is a leftover console.

## Why are there multiple copies?

Several mmc.exe copies are several consoles. That is not several services.exe processes and not several Settings apps.

## Is it safe?

Usually safe

System32 mmc.exe is Microsoft Management Console. An mmc.exe in Downloads is not. This is still not SystemSettings and not services.exe.

A legitimate copy normally runs from:

`C:\Windows\System32\mmc.exe`

- Hosts .msc snap-ins
- Settings app: ImmersiveControlPanel\SystemSettings.exe
- Service Control Manager: services.exe

## Can I end it?

Closes that console

Ending mmc.exe closes that snap-in window. services.exe stays. SystemSettings.exe stays. Unsaved console customizations may be lost.

## Can I remove it?

No

Do not delete mmc.exe. You would lose snap-in hosting. Uninstalling a management tool does not remove Settings or SCM.

## Should it start with Windows?

A shortcut to an .msc can start it. services.exe starts with the boot path. That is not this host.

## Normal resource behavior

These are contextual labels, not universal averages.

- **CPU**: Low unless a snap-in is refreshing hard

  **Memory**: Moderate per open console

  **Disk**: Low

  **Network**: Remote snap-ins can talk to another PC

## Common problems

### People end services.exe after closing Services.msc

You closed a snap-in. SCM is a different process. Ending services.exe is how you crash the session.

### They reset Settings because Disk Management would not open

diskmgmt.msc is MMC. Repair the console or the VDS stack. SystemSettings.exe is the wrong app.

## Troubleshooting

Diagnose before you change anything destructive.

### Check the command line for the .msc name

services.msc, eventvwr.msc, diskmgmt.msc. That names the snap-in. Task Manager's own window is taskmgr.exe.

### Author a new console with mmc /a only if the .msc is corrupt

Do not replace services.exe. Do not delete System32\mmc.exe from a zip "fix."
