Hi @IngramQuick-5843
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here. I understand that you are having trouble enabling Windows Admin Center for premise-based systems using Azure Arc. The comment you mentioned means that Microsoft requires devices to be in good working order to obtain a Pay-as-you-go license for Azure services.
Regarding your issue, Windows Admin Center is indeed part of the Azure Arc - core control plane and is free to use. However, there may be other requirements or configurations that need to be met in order to use it with your premise-based systems.
I suggest checking the Azure Arc documentation and making sure that all the prerequisites are met for using Windows Admin Center with your systems. Here is the link to the Azure Arc documentation: https://docs.microsoft.com/en-us/azure/azure-arc/
If you are still having trouble after checking the documentation, I recommend reaching out to Azure Support for further assistance. They can help you investigate the issue and find a solution. You can reach out to them by going to Help + Support in the Azure Portal and selecting Azure Arc as the issue.
If you have any further queries, do let us know
