Hello @Chema Martínez ,
Thank you for posting here.
Q: Do you know how to discover if patch KB4519337 is really compatible with Windows Server 2019?
A: No, patch KB4519337 is not compatible with Windows Server 2019.
From the Microsoft Update Catalog, we can see it applies to Windows 10 1809.
And from the following link, we can see:
Dynamic Update can help organizations and end users alike ensure that their Windows 10 devices have the latest feature update content (as part of an in-place upgrade)—and preserve precious features on demand (FODs) and language packs (LPs) that may have been previously installed. Further, Dynamic Update also eliminates the need to install a separate quality update as part of the in-place upgrade process.
For more information, we can refer to link below.
