SQL Server
This article describes how to set an instance of SQL Server to start automatically in SQL Server by using SQL Server Configuration Manager. During setup, SQL Server is normally configured to start automatically. If this was not done, you can change that setting at any time.
Use SQL Server Configuration Manager
Open SQL Server Configuration Manager from the Windows Start menu.
Because SQL Server Configuration Manager is a snap-in for the Microsoft Management Console program and not a stand-alone program, SQL Server Configuration Manager might not appear as an application in newer versions of Windows.
From the Windows Start menu, type SQLServerManager17.msc (for SQL Server 2025 (17.x)). For other versions of SQL Server, replace 17 with the appropriate number. Selecting SQLServerManager17.msc opens SQL Server Configuration Manager.
You can pin SQL Server Configuration Manager to the Start menu or taskbar when you right-click SQLServerManager17.msc, and then select Open file location. In File Explorer, right-click SQLServerManager17.msc, and then select Pin to Start or Pin to taskbar.
Set an instance of SQL Server to start automatically
In SQL Server Configuration Manager, expand Services, and then select SQL Server.
In the details pane, right-click the name of the instance you want to start automatically, and then select Properties.
In the SQL Server <instancename> Properties dialog box, set Start Mode to Automatic.
Select OK, and then close SQL Server Configuration Manager.
