How can I 'Preview' Powershell Scripts on a Server 2008 R2 server?

Hello,

On a Server 2008 R2 Domain Controller, I have the 'Preview Pane' available and shown, but when I 'hover' over a Powershell script, or a .ps1 file, I get a 'No preview available' in the preview pane.  Preview works for .csv or .txt, but not for .ps1 files.  Any suggestions on how I can preview Powershell scripts?

Thanks for your help! SdeDot
