- Product
- Microsoft 365 F3, Microsoft Defender for Endpoint
- Device & OS
- Windows LTSC
- Scenario
- Administrators are attempting to deploy Microsoft Defender for Endpoint to Windows LTSC machines using frontline worker (F3) licenses.
- Observed behavior
- Microsoft 365 F3 is tailored for frontline workers and does not inherently provide full operating system rights for Windows LTSC, meaning devices may fail to onboard without a separate license.
Verify the exact edition of Windows LTSC installed on your endpoints and review your current active subscriptions in the Microsoft 365 Admin Center.
Verify Licensing Terms and Obtain Required Enterprise Agreements
Use this solution to ensure compliance and properly license your LTSC endpoints for Microsoft Defender onboarding.
Microsoft 365 F3 licenses are strictly designed for frontline workers and generally do not include Windows LTSC operating-system rights. To successfully onboard these devices to Microsoft Defender for Endpoint, an alternate or supplementary licensing arrangement is required.
Review the specific Windows LTSC edition installed on your devices by navigating to Settings > System > About on the endpoint.
Consult the official Microsoft Defender for Endpoint documentation to confirm the exact licensing SKUs supported for your specific Windows LTSC build.
Contact your Microsoft account representative or Volume Licensing provider to acquire an eligible Windows Enterprise license or standalone Defender for Endpoint licenses for the LTSC devices.
