List installed roles and features in Server Core 8

Tested on Windows Server 8 Developer Preview.

On the 2008 R1 and R2 versions of Server Core, we could list all the roles and features using the OCList command.  This gave us a large and messy list.  We can use PowerShell to give us a list of what is installed, and separately what is not.
At the command prompt, type PowerShell and press Enter.

We need to expand the normal cmdlet set for PowerShell by importing the ServerManager module.

Import-Module ServerManager

To get a list of all installed components:

Get-WindowsFeature | Where {$_.Installed –eq $True}
image

Conversely, we can also get this list of roles and features that are not installed.
Get-WindowsFeature | Where {$_.Installed –eq $False}

I have a dumb question. When I go into PowerShell and type "Import-Module ServerManager" I get an error message that ServerManager was not loaded because no valid module file was found in any module directory. Where do you get ServerManager from?
Kathleen,

Make sure you are using Windows Server Core 8. This does not work on Windows Server 2008 R2 Core.

Adding a Comment to a GPO with PowerShell

As I'm writing this article, I'm also writing a customization for a PowerShell course I'm teaching next week in Phoenix.  This customization deals with Group Policy and PowerShell.  For those of you who attend my classes may already know this, but I sit their and try to ask the questions to myself that others may ask as I present the material.  I finished up my customization a few hours ago and then I realized that I did not add in how to put a comment on a GPO.  This is a feature that many Group Policy Administrators may not be aware of. This past summer I attended a presentation at TechEd on Group Policy.  One organization in the crowd had over 5,000 Group Policies.  In an environment like that, the comment section can be priceless.  I always like to write in the comment section why I created the policy so I know its purpose next week after I've completed 50 other tasks and can't remember what I did 5 minutes ago. In the Group Policy module for PowerShell V3, th

Return duplicate values from a collection with PowerShell

If you have a collection of objects and you want to remove any duplicate items, it is fairly simple. # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2   # Remove the duplicate values. $Set1 | Select-Object -Unique 1 2 3 4 5 6 7 What if you want only the duplicate values and nothing else? # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2   #Create a second collection with duplicate values removed. $Set2 = $Set1 | Select-Object -Unique   # Return only the duplicate values. ( Compare-Object -ReferenceObject $Set2 -DifferenceObject $Set1 ) . InputObject | Select-Object – Unique 1 2 This works with objects as well as numbers.  The first command creates a collection with 2 duplicates of both 1 and 2.   The second command creates another collection with the duplicates filtered out.  The Compare-Object cmdlet will first find items that are diffe
