WillB123​  If you qualify for Windows Autopatch (Prerequisites | Microsoft Learn), follow the deploy guidance to create Autopatch groups and assign devices into those groups (Windows Autopatch groups overview | Microsoft Learn). Once devices on onboarded into Autopatch you should see the information you are looking for work its way into the Autopatch reports. 

The Feature update status report shows the status of devices that are currently being targeted by a Feature Update - look to see what Feature Update policy you currently have active and targeting devices. The Update Readiness report is the hypothetical - of the devices in my environment, if I were to target them with the Feature Update I selected (Win 11 24H2), which devices are "ready" (low risk), and which are in a risky state. The summary report here does not have the details of the unknowns - you may need to export the report with its columns to be able to identify your unknowns and go from there.
