SQL Server Login After Windows 10 upgrade

With my SQL Server installation and login prior to the upgrade, I had no problems. But after the upgraded, I get:
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. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft%20SQL%20Server&EvtSrc=MSSQLServer&EvtID=-1&LinkId=20476

Q: After reading the link, my first guess was "The SQL Server Browser service (sqlbrowser) is not started." but when I checked, I had:services

Did you check the SQL Server service account? Windows 10 may change the way those internal accounts are working now.

Hi Vitor,

I am not sure how exactly I could do that. You may want to give me some direction on the link below.

Thanks,

Mike

BTW, after deleting to followup question referred in my last post, I posted a new question to better describe the problem at https://www.experts-exchange.com/questions/28703696/SQL-Server-2014-firewall-setting.html
Your help has saved me hundreds of hours of internet surfing.
