After installing Virtuozzo updates, no new Microsoft updates are detected by the node. No error message is returned by the Windows Update service.
The Virtuozzo containers node is running the Service Pack, which has already reached Service Pack Support End Date. When support for a Service Pack ends, Microsoft no longer provides new security updates, hotfixes or other updates for it. For more information please check point 18 of Microsoft Support Lifecycle Policy FAQ.

Contact Microsoft Technical Support for the possibility of providing a custom fix to cover a critical vulnerability in a EOL OS version.
In case it's not possible to have a patch from Microsoft, the only left solution is a manual data migration. The steps to complete it include:
- Deploy a new Virtuozzo containers host on the Windows OS that is currently supported.
- Create the same amount of containers with the same configuration (.conf files can be copied as-is from the source node).
- Install the same set of applications into all containers. In case the applications existed as templates, it is required to recreate them anew on the target OS.
- Use application-specific instructions to migrate the data from source containers.
