This query is used to find Azure Virtual Machines that are running the Windows operating system, but do not have the Azure Hybrid Benefits license type enabled.The Azure Hybrid Benefits program allows users to save money on Windows licenses by using their existing on-premises licenses for Windows Server. When a Virtual Machine is running Windows, but does not have the Azure Hybrid Benefits license type enabled (i.e., the licenseType property is null), it means that the user is not taking advantage of this cost-saving program.The query returns the names of all Virtual Machines that meet these criteria, allowing users to identify which machines are not using Azure Hybrid Benefits and potentially saving money on Windows licenses.For more information on Azure Hybrid benefits please see this link:https://learn.microsoft.com/en-us/windows-server/get-started/azure-hybrid-benefit
