A long time ago in a galaxy far, far away, SQL Server Management Studio was included as part of the SQL Server installer.
Back then, upgrading SSMS was not only a technical problem, but a political one too. Organizations would say things like, “Sorry, we haven’t certified that cool new SQL Server 1982 here yet, so you can’t have access to the installer.” Developers and DBAs were forced to run SSMS from whatever ancient legacy version of SQL Server that their company had certified.
Working in a controlled industry, I still get to hear that answer.
