SharePoint Server gets its own updates, separate from Windows, once a month on Patch Tuesday. Which one is for your farm depends on the SharePoint Server version: Subscription Edition, 2019 or 2016. Office Online Server, which runs on its own servers next to SharePoint, has updates of its own.
The quickest way: SharePoint Management Shell
On a SharePoint server, open the SharePoint Management Shell as an administrator and run:
> (Get-SPFarm).BuildVersionIt prints the build of the farm, for example 16.0.20326.20136. The version follows from the build:
| Version | Build |
|---|---|
| SharePoint Server Subscription Edition | 16.0.14xxx and later |
| SharePoint Server 2019 | 16.0.10xxx |
| SharePoint Server 2016 | 16.0.4xxx and 16.0.5xxx |
The command prints version numbers only, nothing about your sites or users. In Central Administration, Upgrade and Migration > Check product and patch installation status lists the updates installed on each server.
Office Online Server
On an Office Online Server machine, run in PowerShell:
> Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* |> Where-Object DisplayName -like 'Microsoft Office Online Server*' |> Select-Object DisplayName, DisplayVersion
DisplayVersion is the build, for example 16.0.10417.20083.
Two packages for SharePoint Server 2019 and 2016
Each monthly release of SharePoint Server 2019 and 2016 comes as two KBs: the update itself and a language pack update. Install both on every server of the farm, then run the SharePoint Products Configuration Wizard (or PSConfig.exe). Subscription Edition and Office Online Server have one package a month.
