Summary: Use Windows PowerShell to discover what features do in Windows 8.

 I found five different Hyper-V features on my Windows 8-based computer, and I want to know how I can use Windows PowerShell to discover what they do.

 Use the Get-WindowsOptionalFeature cmdlet and select the feature name and the description of the feature
          (this is a single-line command broken for readability at the pipeline character):

Get-WindowsOptionalFeature -Online -FeatureName ‘*hyper-v*’ |

select featurename, description | Format-Table -AutoSize -Wrap
