December 2020 CU for SharePoint Server 2019 is available for download

The product group released the December 2020 Cumulative Update for SharePoint Server 2019 product family. SharePoint Server 2019 is patched with a language dependent and a language independent fix.

The KB article for December 2020 CU will be available at the following Location in a couple of hours:

  • KB 4486751 – December 2020 Update for SharePoint Server 2019 (language independent) – This is also a security update!
  • KB 4486752 – December 2020 Update for SharePoint Server 2019 (language dependent) – This is also a security update!

The download for December 2020 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 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 December 2020 CU Build Number:

Language independent fix: 16.0.10369.20000
Language dependent fix: 16.0.10369.20000

  1. Greetings, Stefan. I just applied the December 2020 CU to our SharePoint 2019 farm and the Current Nav is no longer showing in Chrome or the new Edge but still visible in IE and older Edge. I saw one article through research that said this was happening as soon as August but we’ve had all the monthly patches up to December and the Current Nav displayed just fine. Is Microsoft aware of the issue and working on a resolution to it? Thank you.

    1. Hi Daniel,
      I have seen a similar issue before which was caused by old files being stored in the browser cache.
      Can you please clear the browser cache and try again to see if that solves the issue?
      Cheers,
      Stefan
