You can use Configuration Manager to start, pause, resume, or
stop SQL Server–related services. The services available depend on the specific
components of SQL Server you have installed, but you should always have the SQL
Server service itself and the SQL Server Agent service. Other services might
include the SQL Server Full-Text Search service and SQL Server Integration
Services (SSIS).
You can also use Configuration Manager to view the current properties of the services, such as whether
the service is set to start automatically. Configuration Manager is the
preferred tool for changing service properties rather than using Windows
service management tools. When you use a SQL Server tool such as Configuration
Manager to change the account used by either the SQL Server or SQL Server Agent
service, the SQL Server tool automatically makes additional configurations, such
as setting permissions in the Windows Registry so that the new account can read
the SQL Server settings. Password changes using Configuration Manager take
effect immediately without requiring you to restart the service.
