 ## Overview
 
-Microsoft Intune only supports managing Windows 10 or Windows 11 Enterprise multi-session with device configurations. This means only [policies defined in the OS scope](/windows/client-management/mdm/policy-configuration-service-provider) and apps configured to install in the system context can be applied to Azure Virtual Desktop multi-session VMs. Additionally, all multi-session configurations must be targeted to devices or device groups. User scope policies are not supported at this time.
