Catalog search terms vmms, hyper-v virtual machine management, vmms service

Windows, System Component

Hyper-V Virtual Machine Management Service. E dey manage Hyper-V VMs for SKUs wey get Hyper-V. E no be WSL wslservice.exe.

## Wetin you need know

vmms na Hyper-V management, no be WSL wslservice.

vmms.exe na Virtual Machine Management Service. Hyper-V Manager dey talk here. wslservice.exe dey coordinate WSL distributions. vmcompute.exe na Host Compute Service. Ending vmms no dey shut down Ubuntu the way \`wsl --shutdown\` dey do.

- **E safe?**: Check the running file path, signature, and publisher. Name alone no fit confirm say e safe.

  **Same thing as wslservice?**: No. Dis one na Hyper-V management

  **I suppose end am?**: Hyper-V VMs dey lose management

Feex tok say

If I see vmms on top SKU with Hyper-V, I dey treat am as VM management. I no dey find Ubuntu inside dis process, and I no dey end wslservice to stop Hyper-V Manager.

## Wetin be vmms.exe?

vmms na for Hyper-V management, no bi WSL wslservice. Na im bi di Virtual Machine Management Service. wslservice.exe dey only coordinate WSL. To switch dose names dey wrong.

## Wetin e dey do?

E dey create, start, and configure Hyper-V VMs. Worker processes na vmwp.exe, one for each VM wey dey run. E no dey host \`wsl -l -v\`.

## Wetin make am dey run?

Hyper-V dey installed and sometin open di management stack. Home SKUs wey no get Hyper-V no suppose show normal System32 vmms.

## Inspect the running instance

Inside Windows PowerShell, this read-only query show matching process IDs, creation times and executable paths on this PC. (pcm)

`Get-CimInstance -ClassName Win32_Process | Where-Object { $_.Name -eq 'vmms.exe' } | Select-Object ProcessId, ParentProcessId, CreationDate, Name, ExecutablePath | Format-List`

No result or a path we no fit access is inconclusive. Protected processes fit restrict access, and process IDs fit be reused. Keep personal paths local. (pcm)

Use the [file-identity guide](https://feex.it/wiki/l/pcm/software/system/verify-executable-path-signature/) to compare signatures and product metadata. A filename alone no fit establish safety. (pcm)

## E dey safe?

Check dis running file

System32 vmms.exe na Hyper-V VMMS. Any vmms.exe inside Downloads no bi am. Dis one still no bi WslService.

Compare the recorded location with the actual file. A familiar folder alone no fit establish identity. (pcm)

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

- Service: Hyper-V Virtual Machine Management
- Workers: vmwp.exe, one for each VM
- No be wslservice.exe

## I fit end am?

Hyper-V management go drop

To end vmms.exe dey disconnect Hyper-V Manager and fit hang VM control. Running vmwp copies fit still remain. Dat one no bi \`wsl --shutdown\`.

## I fit comot am?

Comot di Hyper-V role, no bi di file

Off Hyper-V from Windows features if you no want VMMS. No delete System32\vmms.exe. To uninstall WSL no dey comot dis service.

## E suppose start with Windows?

Di vmms service dey start wen Hyper-V need management. E no bi WSL Startup entry.

## Measure resource use

| CPU and memory   | Compare several observations for the same PID and workload. This entry get no independently measured universal baseline. (pcm)               |
| ---------------- | -------------------------------------------------------------------------------------------------------------------------------------------- |
| Disk and network | Attribute activity to the actual process and current task; a filename alone no fit establish expected destinations or transfer volume. (pcm) |

| Signature check            | Inspect the actual file; this entry no dey certify its certificate identity. (pcm) |

## Common wahala dem

### People dey stop WslService to close Hyper-V Manager

Hyper-V Manager dey talk to vmms. WSL get im own service. Two consoles, two processes.

### VMs still dey run afta dem end vmms

vmwp.exe na di worker for each VM. Management don die. Di guest fit still dey on top di worker.

## How to troubleshoot

Diagnose before you change anything wey fit scatter things.

### Hyper-V Manager and services.msc: Virtual Machine Management

If dat snap-in fail, na dis service bi di article. Make wsl -l -v fail na wslservice, no bi vmms.

### No disable Host Compute Service to "fix Hyper-V"

vmcompute na HCS. Repair or restart vmms for classic VMs. Leave System32 files where dem dey.
