Microsoft has fixed a bug blocking some Azure Virtual Desktop devices from downloading and installing monthly security via Windows Server Update Services since early July.
Microsoft also provides two workarounds that allow customers to apply monthly security updates on Azure Virtual Desktop systems using WSUS if they can't immediately deploy the KB5005565 CU that fixes the known issue.
The first workaround requires deploying up-to-date images to all impacted devices, including all Azure Marketplace security updates.
The second approach, needed on computers where image redeployment is not an option, requires manually downloading and installing the missing security updates from the Microsoft Update Catalog.
"Microsoft publishes monthly security updates on the second Tuesday of each month. You can download these updates from the Microsoft Update Catalog as Microsoft Update files and deploy them using your management solution," Microsoft says.
Msu files to your endpoint management system and start deploying the security updates to devices running Windows 10 Enterprise or Education, version 1909.
