There are 2 problems you are facing
- Unable to connect to SQL Server
- SSCM not available.
For 1st issue you can refer to 2102.how-to-troubleshoot-connecting-to-the-sql-server-database-engine.aspx
For 2nd issue, you can go to services and find SQL Server configuration manager and manage it, although not completely.
I would like to know your exact issue
EDIT: Taking cue from @tibor_karaszi@hotmail.com answer. I completely missed your question I guess. Yes for windows 10 you have different way to launch SSCM. Microsoft has documented it
To open SQL Server Configuration Manager, on the Start Page, type SQLServerManager13.msc (for SQL Server 2016 (13.x)). For other versions of SQL Server, replace 13 with the corresponding number. Clicking SQLServerManager13.msc opens the Configuration Manager. To pin the Configuration Manager to the Start Page or Task Bar, right-click SQLServerManager13.msc, and then click Open file location. In the Windows File Explorer, right-click SQLServerManager13.msc, and then click Pin to Start or Pin to taskbar.
