Registering a server in SQL Server Management Studio allows you to store the server connection information for future connections.There are three ways to register a server in SQL Server Management Studio.
Local instances of SQL Server are automatically registered during the first launch of Management Studio after its installation.
You can also initiate the automatic registration process at any time, to restore the registration of local server instances.
