The product group released the February 2019 Cumulative Update for SharePoint Server 2016 product family. Be aware that only a language independent fix was released with February 2019 CU. The latest language dependent fix was released with October 2018 CU.

  • KB 4462155 - February 2019 Update for SharePoint Server 2016 (language independent) - This is also a security update!
  • There was no language dependent fix released for SharePoint 2016 in February.
  • There was no fix released for Office Online Server 2016 in February.

The download for February 2019 CU is available through the following link:

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 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.

SharePoint 2016 February 2019 CU Build Numbers:

Language independent fix: 16.0.4810.1000

To understand the different version numbers please have a look at my article which explains the different SharePoint build numbers.

You can use the SharePoint Server 2016 Patch Build Numbers Powershell Module to identify the patch level of all SharePoint components.

    Can I apply the October language dependent update directly after updating to February language independent update? My farm is currently on august updates and I want to update to February. Do I need to install the October language independent update prior to the language dependent one?

    1. Yes, you can apply the language dependent October patch after installing the language Independent February CU.

    My environment is already in October 2018 CU. I am planning to upgrade to Jan 2019 CU. In that case, do i need to just apply the language independent pack released in Jan or should i reapply the Language dependent pack from October 18 CU together with the language independent pack from Jan 2019 CU?

    1. Just install the language Independent Jan 2019 fix.
      No need to reapply the language dependent if you did not meanwhile install a new language pack.
