My laptop came with SQL Server 2016 and for past 2 months I was able to develop within localhost just fine. Now, during a 2 week pause (away from SQL Server) I have returned to it, installed recommended updates, and now find I can't connect to localhost ...
Discovered Aaron Bertrand's advise for connecting to SQL Server Configuration Manager at this link http://stackoverflow.com/questions/12774827/cant-connect-to-localhost-on-sql-server-express-2012-2016 but I can't connect to Config Manager either.
I perceive that if I can connect to Config Manager then I will be able to activate localhost and be back to work.
Will someone please walk me through to connecting Config Manager and ultimately being able to work within localhost again?

You probably want to check Services and make sure it's running. Do you know what edition of SQL Server was installed? Were you using LocalDB from SSDT? Try to view the entire error message or check the windows log for the errors. It will be much easier to figure out the issue you can find the error message.

Here's what I get when I check services.

Without being able to run Select @@Version I can't tell you what edition, but it is likely Developer.
Regarding question if I was using LocalDB from SSDT, I am puzzled. SSDT is SQL Server Data Tools, which I only use when building SSRS, SSIS pkgs. So, I think the answer is no.

Below is error I am getting.

===================================

Cannot connect to ..

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

Well, the service is not running. Right click on it in Services, and pick Start.
