During the installation of SQL 2014 the Windows feature 'PowerShell 2.0' will be installed.
It's also mentioned on the website of Microsoft as an 'installation prerequisite' (https://docs.microsoft.com/en-us/sql/sql-server/install/hardware-and-software-requirements-for-installing-sql-server?view=sql-server-2014).
But is PowerShell 2.0 really required? As far a I can see PowerShell 2.0 isn't used by SQL 2014 (sqlps is also working with only PowerShell 5 installed).
My question is: is it safe to remove PowerShell 2.0 on a server (Server 2012R2/2016) with SQL 2014?
