January 2019 CU for SharePoint Server 2019 is available for download

The product group released the January 2019 Cumulative Update for SharePoint Server 2019 product family. If you are familiar with SharePoint Server 2016 you are aware that SharePoint is now patched with a language dependent and a language independent fix. In January we are releasing our first language dependent fix.

The KB article for January 2019 CU will be available at the following Location in a couple of hours:

• Download January 2019 Update for SharePoint Server 2019 (language dependent)
• Download January 2019 Update for Office Online 2019 – This is also a security update!

Important: It is required to install both fixes (language dependent and independent) to fully patch a SharePoint server. This applies also to servers which do not have language packs installed. The reason is that each SharePoint installation includes a language dependent component together with a language independent component. If additional language packs are added later (only) the language dependent fix has to be applied again.

It is irrelevant which language you pick on the drop down in download center. Even the language dependent fixes are all in the same package for all languages.

After installing the fixes you need to run the SharePoint 2019 Products Configuration Wizard on each machine in the farm. If you prefer to run the command line version psconfig.exe ensure to have a look here for the correct options.
