The product group released the January 2021 Cumulative Update for SharePoint Server 2019 product family. SharePoint Server 2019 is patched with a language dependent and a language independent fix.

- KB 4493162 – January 2021 Update for SharePoint Server 2019 (language independent) – This is also a security update!

The download for January 2021 CU is available through the following link:
- Download January 2021 Update for SharePoint Server 2019 (language independent) – This is also a security update!
- Download January 2021 Update for SharePoint Server 2019 (language dependent) – 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.
Please ensure to have a look at the SharePoint Patching Best Practices before applying new fixes.
SharePoint 2019 January 2021 CU Build Number:
Language independent fix: 16.0.10370.20001

Hi Stefan,
You are saying: “It is required to install both fixes”. Does it matter which fix must installed first (independent or dependent) ?
Kind regards, Leon B

No it does not matter.
