Going down the IT rabbit hole

Windows Admin Center (WAC) v1 (2311, MSI,…) has it’s own extension feed (https://aka.ms/sme-extension-feed):

With this older version of WAC we are able to extend WAC functionality with support for Configuration Manager Client and Configuration Manager Client Tools. New WAC (WAC v2) is using different extension feed and as of mid-February 2026 this feed doesn’t have Configuration Manager extension.

What happens if we add WAC v1 extension feed to WAC v2?

Hm, it gets successfully added…

But, does it actually work? Well, no…

To get support for old extension feed in WAC v2, we are still missing one key configuration change:

We need to change WAC “operation mode” from “Production” to “Development”. And because this is WAC service configuration file we just changed, we must restart WAC service (Restart-Service -Name WindowsAdminCenter) before we can see this change applied to our WAC portal:

If all goes well, we can now see all “old WAC v1” extensions, including the two for the Configuration Manager Clients:

CM extensions installed side-by-side with new extensions on WAC v2:

Until we meet again…
