Update Center for Microsoft SQL Server
Registration is no longer required to download Cumulative updates. The following link (https://technet.microsoft.com/en-us/library/ff803383.aspx) will take you to the centralized Update Center for Microsoft SQL Server covering all releases (supported and unsupported) and their associated service packs (SP) and latest cumulative updates (CU) from SQL Server 2016 back through SQL Sever 2000 (as of the date of publication of this article.)
Cumulative updates (CU) are now available at the Microsoft Download Center but only the most recent CU that is released for a particular version's service pack of Microsoft SQL Server is to be made available through the Download Center. This is because each new CU contains all the fixes that were included with the previous CU for the installed version/Service Pack of SQL Server. You'll see availability of the latest CU for Service Pack 1 of SQL Server 2016 (CU2) as well as for the RTM release of SQL Server 2016 (CU5) on the Update Center portal.
Additional facts direct from Microsoft about it's current release structure for updates:
- Microsoft recommends ongoing, proactive installation of CUs as they become available and recommends you upgrade your SQL Server installation to the latest SQL Server 2016 service pack.
- SQL Server CUs are certified to the same levels as Service Packs, and should be installed at the same level of confidence.
- Historical data shows that a significant number of support cases involve an issue that has already been addressed in a released CU.
- CUs may contain added value over and above hotfixes. This includes supportability, manageability, and reliability updates.
- Just as for SQL Server service packs, Microsoft recommends that you test CUs before you deploy them to production environments.
SQL Server Pro will continue to provide you with updates on when the latest service packs and cumulative updates are released for Microsoft SQL Server.
