This query finds Windows 11 devices that are enrolled in Defender for Endpoint and retrieves the last user who logged on interactively. It uses the DeviceInfo and DeviceLogonEvents tables from the M365 Defender data connector. The query filters for devices with a recent TimeGenerated, a non-empty OSPlatform, and then groups the results by DeviceName, keeping the latest TimeGenerated for each device. It further filters for devices with OSPlatform "Windows11" or OSBuildString starting with "22" or "21". The final result includes the DeviceName, AccountName (last user who logged on), OSBuild, OSPlatform, and OSVersion.
