The Uninstall-WindowsFeature cmdlet uninstalls and optionally removes specified roles, role services, and features from a computer that is running Windows Server 2012 R2, or from an offline virtual hard disk (VHD) on which Windows Server 2012 R2 is installed. This cmdlet works similarly to the rrfw in Server Manager, with an important exception: by default, management tools are not uninstalled when you run the Uninstall-WindowsFeature cmdlet; you must add the IncludeManagementTools parameter to uninstall associated management tools. This cmdlet requires elevation; you must be running a Windows PowerShell session as an administrator to use this cmdlet.
