A. Server 2008 R2 introduces PowerShell cmdlets for the management of Roles and Features. To use them, you just need to import the ServerManager library in PowerShell:

                              Import-Module servermanager                              

You can now add and remove roles and features using the Add-WindowsFeature and Remove-WindowsFeature cmdlets. To check all the available roles and features and their install statuses, use the Get-WindowsFeature cmdlet. If the feature is installed, an \[X\] is displayed, as the sample below shows.

The name on the right side is the name needed to install or remove the feature. For example,

                              Add-WindowsFeature Hyper-V                              

would install Hyper-V.
