We are investigating an issue where devices running Windows 10 Enterprise multi-session, version 1909 might not be able to download updates later than May 2021. This is observed in the Settings app under the Windows Update setting, which will display the message "You're up to date" even if no updates later than May 2021 have been installed.

Workaround: There are 2 alternatives to resolve this issue. As the latest images from the Azure Marketplace will be up-to-date with all of the security updates, redeployment of images to existing devices will solve this issue. If redeployment is not an option, security updates can still be installed manually on these devices, via downloads from the Microsoft Update Catalog. For instructions, please see KB5004926 and review the Workaround section.

Affected platforms:
  • Client: Windows 10 Enterprise multi-session, version 1909
  • Server: Windows Server multi-session, version 1909
Next steps: We are working on a resolution and will provide an update in an upcoming release.
