SharePoint Server 2019 CU – CU download links:

After installation, remember to run the SharePoint 2019 Products Configuration Wizard or the following command:

PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install

Important notes

Always install both packages in this order:

  1. language independent components (core CU)
  2. language-dependent components (language CU)

For language-dependent packages, the language you select does not matter because each package contains updates for all languages.

If you install a new language pack on a SharePoint Server 2019 farm, you must reinstall the language-dependent update afterwards.

Remember to keep Distributed Cache updated as well as SharePoint. See How to update Distributed Cache correctly (in Czech).
