WSL2 uninstall allows distributions to run without WSL management service and therefore WSL plugins are not active #12202

Repro Steps

  1. Install WSL using the provided MSI from https://github.com/microsoft/WSL/releases
  2. Install a distribution wsl --install -d Ubuntu
  3. Use the distribution wsl
  4. Uninstall WSL wsl --uninstall
  5. Use the distribution wsl

Note: I am not sure if this is an expected configuration or state for WSL or not. I am unable to find any documentation on this. But overall it seems like undesired behavior at best or a potential security vulnerability or bypass at worst.

Expected Behavior

When WSL2 is active on the machine and WSL plugins are registered with the Windows Subsystem for Linux. Starting virtual machines or distribution containers should result in the WSL plugin being notified of this activity.

Actual Behavior

When WSL is "uninstalled"( wsl --uninstall) the WSL2 virtual machines and containers are still allowed to start despite the WSL Service not being installed and active on the system. This results in WSL plugins not being notified of WSL2 activity on the system.

> wsl --list -v
  NAME      STATE           VERSION
* Ubuntu    Running         2

> sc query WSLService
[SC] EnumQueryServicesStatus:OpenService FAILED 1060:

The specified service does not exist as an installed service.

Another consequence of this state is that certain commands do not result in expected:

> wsl --version
[outputs help text?]

>  wsl --update
Installing: Windows Subsystem for Linux
The system cannot find the file specified.

This is by design. If you don't want users to be able to use the inbox version of WSL (which does not support Intune policies) you must set this policy to false.

Allow the Inbox version of the Windows Subsystem for Linux https://learn.microsoft.com/en-us/windows/wsl/intune#recommended-settings
