SQL Server Configuration Manager is not showing SQL Services I have newly installed following things on my system 

     - Microsoft SQL Server Management Studio 2014 
     - SQL Server 2017
     - Visual Studio 2015


When I tried to open SSMS for the first time, it asked me for the "Server Name" when I surfed I came to know that I have to check the instance name in Configuration manager-->Sql Services, but I couldn't find any services running in Configuration Manager, it is showing "There are no items to show"

Secondly, I also tried giving the permissions to my SQL Server services as mentioned in article here,  but couldn't solve my issue.

Also I tried to check find the SQL Server instance name using the sqlcmd -L command, but it didn't show any servers, even though SQL Server is already installed.

What am I doing wrong?
SQLExpress is installed as a named instance. Try connecting to  &lt;server name&gt;\SQLEXPRESS

Or localhost\SQLEXPRESS will work as well.
