There are so many settings in SQL Server Management Studio that it can sometimes make someone nervous. Once of my client sent me email telling that something is not right with their SQL Server 2016 installation. Here is an email which I received:
Hi Pinal,
One of the developer has installed SQL Server 2016 on our development environment. I already had SQL Server 2014 running on the server. I am seeing a strange behavior in SQL Server Management Studio. When I connect from SSMS 2014, I am seeing system views as you can see below.
