WindowsSystem 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 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

Measure the current process rather than assume a universal baseline
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)

File information

vmms.exe file information
Executable name vmms.exe
Recorded installation path C:\Windows\System32\vmms.exe
Publisher Microsoft Corporation
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.
