Azure Automation Hybrid Runbook Worker Supported OS
Hi everyone,
we are currently in the process of updating or environment to Server 2025. Since the mainstream support of Server 2022 ends October this year, we would also like to update our on-premise Azure Automation Hybrid Runbook Worker from 2022 to 2025.
As far as I can see from the https://learn.microsoft.com/en-us/azure/automation/extension-based-hybrid-runbook-worker-install?tabs=windows%2Cps#supported-operating-systems, OS is only supported up to Server 2022, but not Server 2025. Since the mainstream support end is closing in, is there any information on official support for Server 2025 for Azure Automation HRWs? Do you already have one successfully running with Server 2025?
Thanks!
Seems now only supported up to Windows Server 2022

I would separate two things here: what may technically install, and what Microsoft currently documents as supported for production.
For production Hybrid Runbook Workers, I would stay on the documented supported OS list until Microsoft Learn explicitly adds Windows Server 2025 or support confirms it for your tenant/scenario. The safer modernization path is to use extension-based Hybrid Runbook Workers, because agent-based User Hybrid Runbook Workers have been retired.
If you need to move early, I would test Server 2025 in a non-prod worker group with representative runbooks, module versions, managed identity auth, outbound firewall rules, and reboot behavior. But for a supportable production design, keep at least one Windows Server 2022 worker group until the docs catch up.
