Yes. Microsoft SQL Server Express is supported on Windows 11.
From the hardware and software requirements:
- SQL Server 2019 Express, 2022 Express, and 2025 Express all support Windows 11 Home, Pro/Professional, Enterprise, and IoT Enterprise.
- These versions are also supported on Windows 10 and current Windows Server editions.
Ensure that Windows 11 is a 64-bit edition and not running in S mode, and that other general SQL Server requirements (disk, memory, CPU) are met.
