When is Windows Admin Center arc extension reaching GA?

Hello Dominic Brazendale

Yes. Windows Admin Center for Azure Arc–enabled servers is generally available (GA). It reached GA as part of “Windows Server Management enabled by Azure Arc”, which Microsoft announced publicly at Ignite 2024 (November 2024). Windows Admin Center is included in this GA management bundle and is supported for production use.

The confusion usually comes from the Azure portal UI and some Learn pages still showing “Preview” labels. Microsoft documentation clarifies that these labels are documentation/UI lag, not the service support status.

1. Install the extension
   • In the Azure portal, go to your Arc-enabled server resource, pick “Extensions,” then “Add,” and select “Windows Admin Center.”
   • Or use Azure CLI:

          az connectedmachine extension create \
     

--resource-group <RG>
--machine-name <YourArcServer>
--name AdminCenter
--publisher Microsoft.HybridCompute
--extension-type AdminCenter ```

1. Check your versions
   • Azure Arc agent ≥ 1.13.21320.014
   • Windows Admin Center extension ≥ 0.0.0.169
2. Networking requirements
   • No inbound firewall ports needed—connection is via reverse proxy.
   • Ensure outbound HTTPS to: • *.wac.azure.com (or WindowsAdminCenter service tag) • pas.windows.net • *.servicebus.windows.net
3. Permissions
   • To install: Owner/Contributor/Windows Admin Center Administrator Login on the server resource
   • To connect: Reader + Windows Admin Center Administrator Login on the server resource

If you hit any snags, check out the troubleshooting steps in “Remote access with Windows Admin Center for Azure Arc–enabled servers” (restart the HIMDS service, verify incomingconnections.ports via azcmagent config list, etc.).
