Summary: Use Windows PowerShell to produce a list of disabled Windows features.
How can I use Windows PowerShell to see what Windows features are disabled in my installation?
Open an elevated Windows PowerShell console, use the Get-WindowsOptionalFeatures cmdlet, and specify
that you want to run the command online. You may also want to filter the list by disabled state and sort the list,
Get-WindowsOptionalFeature -Online | ? state -eq 'disabled' | select featurename | sort -Descending
Note The ? is an alias for the Where-Object cmdlet.
