Frequently asked questions

When does SQL Server 2025 support end?

Microsoft's mainstream support runs until 6 January 2031 and extended support (security fixes) runs until 6 January 2036.

What is the latest SQL Server 2025 build?

Microsoft's newest public release for SQL Server 2025 came out on 22 October 2026: 17.0.5035.5 (CU10).

How do I find my instance's build?

Run SELECT @@VERSION or SELECT SERVERPROPERTY('ProductVersion') in SSMS: the number starts with the version (11 for 2012, 12 for 2014, 13 for 2016, 14 for 2017, 15 for 2019, 16 for 2022, 17 for 2025). Paste it in the box above.

CU or GDR: what is the difference?

A GDR carries security and critical fixes only. A cumulative update (CU) also carries every functional fix. Once a CU is installed, stay on the CU branch (CU + GDR) for later security fixes.
