Feex tok say
If I see wslservice beside Ubuntu, I dey treat dat as the coordinator. I dey run wsl -l -v when I want the CLI mata. I no dey end wsl.exe come talk say WslService don die.

You open distro, Docker Desktop, VS Code WSL, or another client call ILxssUserSession. Quiet service afta `wsl --shutdown` na expected tin.

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 'wslservice.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

Microsoft-signed copy under WindowsApps MicrosoftCorporationII.WindowsSubsystemForLinux or System32 na WslService. wslservice.exe inside Downloads no be dat. This file still no be wsl.exe.

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

C:\Program Files\WindowsApps\MicrosoftCorporationII.WindowsSubsystemForLinux_*\wslservice.exe

  • Dem also dey see am as System32\wslservice.exe on some builds
  • Service name: WslService
  • CLI sibling: wsl.exe, no be this image

I fit end am?

Dey stop WSL sessions

To end wslservice.exe dey tear down the coordinator. Distributions wey dey run go exit. Dat one no be to close wsl.exe, and e no be to end wslhost for one distro.

I fit comot am?

Uninstall WSL, no be random exe

Turn Windows Subsystem for Linux off from Optional features or uninstall the WSL Store package. No delete System32 or WindowsApps by hand. To commot wsl.exe no dey commot WslService.

Common wahala dem

People dey kill wsl.exe dey tink say dem don stop the service

The CLI dey exit. WslService fit keep the VM and other distros alive. Use wsl --shutdown if you want make the coordinator quiet.

How to troubleshoot

Diagnose before you change anything wey fit scatter things.

wsl -l -v from prompt, no be Task Manager on top wsl.exe

State and version dey stay on the CLI. wslservice na the session 0 host wey those commands dey talk to.

If the service refuse to start, repair the WSL Store package. No replace wslhost.exe to "fix" WslService.
