WSUS Windows 11 Feature Update Fails

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.

Thank's I'll give this a shot. I made the change so I'll see how the client responds. Huge fan of your work by the way! Maintenance with WSUS was a nightmare until your tool came into the picture.

If you have WAM, you can open the WAM Shell and run

Add-ESDMimetype
Reset-ESDMimetype
Remove-ESDMimetype

See the included PDF Documentation on these or use the built-in PowerShell Help (Get-Help <command>)

Hi Adam. After changing the Mimetype, the update worked on retries. Thanks again!!

Hello

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

https://social.technet.microsoft.com/Forums/office/en-US/c87e015a-63b8-425f-abb7-5a8828e390bb/wsus-clients-unable-to-find-resource-reportingeventclient167?forum=win10itprosetup

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.

Thanks. I'm aware of the upgrade requirement. The failing clients were running 21H1. My challenge was that while others didn't have the Mimetype at all, I did with a different value. So I was just unsure if I was to edit it especially since I couldn't really find any resources specific to Server 2019. I made the change so I'm observing the behaviour now.

Thanks again!
