  • There was no language dependent fix released this month. The most recent language dependent fix is KB 4461507 from April 2019

The download for May 2019 CU is available here:

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.

  1. Hi Stefan – does this package include a uber file or is it necessary to install previous CUs as well?


    1. Hi Hardy,
      there are no Uber packages for SP2016 or SP2019.
      But the patches are still cumulative. So you need to install the most current language independent and the latest language dependent fix to have a fully patched server.


      1. Hi Stefan – I already thought this but I was confused by a information somewhere else on the Internet – so thank you for the fast response and for the clarification.
