Here's a tip from my book Training Guide: Installing and Configuring Windows Server 2012 from Microsoft Press that shows how to display a list of all installed roles and features on Windows Server 2012:

To display a list of all installed roles and features on the server, pipe the output of the preceding command into the Where-Object cmdlet and use Where-Object to filter out everything except roles and features whose InstallState property is equal to Installed:
Get-WindowsFeature -ComputerName SEA-SRV-1 | Where-Object InstallState -eq Installed
You can narrow your results even further by using the -name parameter of the Get-WindowsFeature cmdlet to select only roles and features that begin with “Print” like this:
Get-WindowsFeature -Name Print* -ComputerName SEA-SRV-1 | Where-Object InstallState -eq Installed
