After installation, remember to run the SharePoint 2019 configuration wizard (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
Always install both packages in this order:
- language independent (updates language-independent components)
- language dependent (updates language-dependent components)
For language-dependent packages (language dependent), it does not matter which language you select, because each package contains updates for all languages.
If you install a new language pack on a SharePoint Server 2019 farm, you must subsequently reinstall the language-dependent package (language dependent).
Remember that, in addition to SharePoint, the Distributed Cache service must also be updated; see How to update Distributed Cache correctly and, for Office Online Server, you must have the current RTM version; see How to update Office Online Server.
Included fixes and improvements
The list of fixes and improvements in this CU consists of excerpts from official Microsoft KB articles in their original language (EN).
