On a Windows Server 2012 or 2012 R2 system you can install the ServerManager module and use the Get-WindowsFeature cmdlet to discover the installed features. They can be managed with Install-WindowsFeature and Uninstall-WindowsFeature .

These cmdlets don’t exist on Windows 8/8.1

However the Dism (Deployment Image Servicing and Management) module can help out. The Dism module is mainly concerned with managing wim files and virtual disks for deployment scenarios but it also contains these cmdlets:

Enable-WindowsOptionalFeature

Get-WindowsOptionalFeature

Disable-WindowsOptionalFeature

To discover the installed features

Get-WindowsOptionalFeature -Online | Format-Table –AutoSize

The output looks like this

FeatureName                                                             State

———–                                                                      —–

Microsoft-Hyper-V-All                                           Enabled

Microsoft-Hyper-V-Tools-All                                Enabled

Microsoft-Hyper-V                                                  Enabled

Microsoft-Hyper-V-Management-Clients           Enabled

Microsoft-Hyper-V-Management-PowerShell    Enabled

Printing-Foundation-Features                               Enabled

Printing-Foundation-LPRPortMonitor                Disabled

Printing-Foundation-LPDPrintService                 Disabled

Printing-Foundation-InternetPrinting-Client     Enabled

etc

For all of these cmdlets use –Online to access the local machine rather than an image.

Individual features can be enabled or disabled

Enable-WindowsOptionalFeature -FeatureName TelnetClient –Online

Disable-WindowsOptionalFeature -FeatureName TelnetClient –Online

Feature names are case sensitive.
