If you are like me connecting to various database sever with your laptop, after a couple of months, you find your "Connect to Server" dialog box filled with many connections not useful anymore.
For a long time, it has been complex to delete the unwanted connections but since SQL Server 2012 it is actually quite easy even if poorly documented!
The trick to delete the dead servers from the list is to select the name you want to delete either via mouse or via keyboard and press the delete key on the keyboard. Note that the text in the box will remain to your last selection even after delete.
