A new cumulative update (January 2022 CU) has been released for SharePoint Server 2016.

This CU includes both Feature Pack 2, available since the September CU (September 2017 CU), and the earlier Feature Pack 1.

SP Build:
16.0.5266.1000 (Language independent CU)
16.0.5266.1000 (Language dependent CU)

SharePoint 2016 CU – KB articles describing the CU:

  • KB 5002113 – January 2022 Update for SharePoint Server 2016 (language independent)
  • KB 5002118 – January 2022 Update for SharePoint Server 2016 (language dependent)

SharePoint Server 2016 CU – CU download links:

After installation, remember to run the SharePoint 2016 Products Configuration Wizard or the following command:

PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install

Important notes

Always install both packages in this order:

  1. language independent components (core CU)
  2. language-dependent components (language CU)

For language-dependent packages, the language you select does not matter because each package contains updates for all languages.

If you install a new language pack on a SharePoint Server 2016 farm, you must reinstall the language-dependent update afterwards.

Remember to keep Distributed Cache updated as well as SharePoint. See How to update Distributed Cache correctly (in Czech).

Note for this CU:

Both updates require the release version of SharePoint Enterprise Server 2016.

Enabling the modern OneDrive for Business experience, through this update or manually, requires active Software Assurance at that time. If that requirement is not met, disable the modern experience.
