The product group released the January 2018 Cumulative Update for SharePoint Server 2016 product family.
This CU also includes Feature Pack 1 which was released with December 2016 CU and Feature Pack 2 which was released with September 2017 CU.
The KB articles for January 2018 CU are available at the following location:
- KB 4011642 – January 2018 Update for SharePoint Server 2016 (language independent) – This is also a security update!
- KB 4011645 – January 2018 Update for SharePoint Server 2016 (language dependent fixes)

The download for January 2018 CU is available through the following link:
- Download January 2018 Update for SharePoint Server 2016 (language independent) – This is also a security update!
- Download January 2018 Update for SharePoint Server 2016 (language dependent fixes)
- Download January 2018 Update for Office Online Server 2016 – This is also a security update!
Important: It is required to install both fixes to fully patch a SharePoint server as each SharePoint installation comes with a language independent component and a language dependent 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 2016 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.
