Based on the provided context, it is possible to onboard your HP EliteDesk Home server running Windows Server 2022 to Azure Arc using the Azure Arc Setup wizard. The wizard automates the onboarding process by checking the necessary prerequisites for successful Azure Arc onboarding and fetching and installing the latest version of the Azure Connected Machine (AzCM) agent. Once the wizard process completes, you're directed to your Windows Server machine in the Azure portal, where it can be viewed and managed like any other Azure Arc-enabled resource. However, it's important to note that Azure Arc Setup is an optional component for Windows Server 2022 and later, so you may need to check if it's already installed or install it separately.
It's also worth noting that Azure Arc is not designed for hosting MMO games. Azure Arc is a management solution that allows you to manage servers and services across on-premises, multi-cloud, and edge environments from a single control plane. If you're looking to host a game, you may want to consider other hosting solutions that are specifically designed for gaming workloads.
