WSUS Windows 11 Feature Update Fails

Question

I've set up WSUS on a Server 2019 machine and clients are meant to pull updates from it. However, I am having trouble getting the feature update to Windows 11 to work. It fails and the error presented on WSUS is "(Unable to Find Resource:) ReportingEvent.Client.167; Parameters: Upgrade to Windows 11 (consumer editions) en-us x64"

I saw previous threads about creating the .esd mimetype set to application/octet-stream but I'm not sure if that applies to me. My IIS already has the .esd mimetype but it is set to application/vnd.ms-cab-compressed.

Any help would be appreciated.

Yes, it does. Many people have mixed results.

Answer 2

Hello

Yes, I would recommend to check up on the Mimetype, following the article below.

But all in all, I would recommend you to check if you devices are already in a OS version eligible for the update (previous versions can't just jump into Windows 11 update), Your PC must have Windows 10, version 2004 or higher installed.
