Evaluate compliance for Windows Subsystem for Linux

  • Artikkeli

Applies to:

  • Windows 10
  • Windows 11

Create a Microsoft Intune policy that checks the compliance of devices running Windows Subsystem for Linux (WSL). Microsoft Intune incorporates the WSL compliance results into the overall compliance state of the host device so that you can see the whole health of the device.

This article describes how to set up compliance checks for WSL.

Requirements

To create your compliance policy with WSL settings, you must meet these requirements:

  • The Intune WSL plugin must be installed for compliance evaluation.

  • The Microsoft Intune management extension must be installed on the target device. Make sure devices meet one of the following conditions so that the management extension can install:

    • Assign a PowerShell script or a proactive remediation to the user or device.
    • Deploy a Win32 app or Microsoft Store app to the user or device.
    • Assign a custom compliance policy to the user or device.

Before you begin

Unassign and remove existing custom compliance policies for WSL. Then review the limitations with WSL settings in compliance policies so that you know what to expect.

Add Intune WSL plugin as a Win32 app

Create a Win32 app policy for the Intune WSL plugin, and assign it to the target Microsoft Entra group.

  1. Use the Microsoft Win32 Content Prep Tool to convert the Intune WSL plugin to the .intunewin format. For more information, see Convert the Win32 app content.

  2. Sign in to the Microsoft Intune admin center as at least an Intune administrator.

  3. Go to Apps > All apps > Add.

  4. For App type, scroll down to Other, and then select Windows app (Win32).

  5. Choose Select. The Add app steps appear.

  6. Choose Select app package file.

  7. Select the Folder button and browse your files for the app package file. Upload the Intune WSL plugin installation file with the .intunewin extension.

  8. Select OK to continue.

  9. Enter the following app information:

    • Select file: The app package file you selected in the previous step appears here. Select the file to upload a different installation package file for the Intune WSL plugin.
    • Name: Enter Intune WSL Plugin.
    • Description: Select Edit Description to enter a description for the app. For example, you can describe its purpose or how your organization plans to use it. This setting is optional but recommended.
    • Publisher: Enter Microsoft Intune.

  10. Select Next to go to Program.

  11. Review the settings that are prepopulated so that you're familiar with how the app behaves. Leave the settings as-is.

  12. Select Next to go to Requirements.

  13. Enter the requirements devices must meet to install the app.

  14. Select Next to go to Detection rules.

  15. Review the detection rules that are prepopulated. These rules are app-specific and detect the presence of the app. Leave the settings as-is.

  16. Select Next to go to Dependencies. Leave the settings as-is.

  17. Select Next to go to Supersedence. Leave the settings as-is.

  18. Select Next to go to Assignments.

  19. To assign the policy, add Microsoft Entra users under Required.

  20. Select Next to go to Review + create.

  21. Review the summary, and then select Create to save the policy.

Note

When you create a compliance policy with WSL settings, it automatically generates a read-only custom script. Editing the compliance policy also edits the associated custom script. These scripts appear in the Microsoft Intune admin center in Devices > Compliance > Scripts and are called Built-in WSL Compliance-< compliance policy id >.

Limitations

This section describes the known limitations with using the Intune WSL plugin for compliance evaluation.

  • Compliance evaluation requires the installed Linux distributions in WSL to run at least one time before it works. If you install a Linux distribution with the --no-launch command for WSL, the compliance evaluation won't work.

  • Compliance evaluation might not function as expected on custom Linux images or Linux images without the etc/os-release directory.

  • Even with the Intune WSL plugin, it's possible for malicious software or user actions to compromise the compliance evaluation mechanism.
