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.

Please ensure to have a look at the SharePoint Patching Best Practices before applying new fixes.

  1. Hello Stefan,

    one of our customer is using “Side-by-Side” Patching.
    It seems like that the CU installation will create the folder “16.0.10357.20004” in C:\Program Files\Common Files\microsoft shared\Web Server Extensions\16\TEMPLATE\LAYOUTS

    But the current SharePoint version with March 2020 CU is 16.0.10357.20002.

    After installing the cu and running psconfig i set the “SideBySideToken” to the version 16.0.10357.20004
    $webapp.WebService.SideBySideToken = “16.0.10357.20004”

    I just want to ask if it’s correct that the folder name in the layouts-folder for the March 2020 with “20004” is really correct?

    Thank you in advance,


    1. Hi Stephan,
      the language dependent fix has version 16.0.10357.20004 while the language independent one has 16.0.10357.20002. The highest build version wins.
      So everything is fine and as expected.
