SQL Server Configuration Manager - Where is it?
Are you trying to find SQL Configuration Manager to start and stop or configure SQL Services.
Well its been removed from the start menu but its still available. You can read about the change here https://docs.microsoft.com/en-us/sql/relational-databases/sql-server-configuration-manager
Essentially you need to type SQLServerManager<version>.msc where version is the version you have installed. SQL 2008 = 10, SQL 2016 = 13.
You can create a shortcut to replace the one that was removed and put it on your desktop to make it easier to find it.
