SQL Server 2012 can't start because of a login failure

Question

I recently installed Microsoft SQL Server 2012 on a fresh Windows 7 installation, but whenever I want to run the server, I get the following error:

Error

Answer 1

I had a similar issue that was resolved with the following:

1. In Services.MSC click on the Log On tab and add the user with minimum privileges and password (on the service that is throwing the login error)
2. By Starting Sql Server to run as Administrator

If the user is a domain user use Domain username and password
