Here’s the release history for Microsoft SQL Server 2016. Each update is linked to its Microsoft knowledge base article with the download and the list of hotfixes included.
|Service Pack||Cumulative Update||Release Date||Build||Support Ends|
|CU2 (see note 1 and note 2)||2016/09/22||13.0.2164.0||2026/07/14|
Note that you can also spend more and get Premium Assurance for even longer support than we show here.
Note 1: CU2 has a known issue with Filestream not working when SecureBoot is enabled. If you’re on Windows Server 2016 or Windows 10, and you’re using SecureBoot (which is enabled by default with Hyper-V Gen2 VMs), and your database has Filestream, you either need to disable SecureBoot, or skip CU2 for now.
Note 2: columnstore index users should consider the on-demand hotfix update 13.0.2170.0, which includes serious performance and reliability fixes.
