SharePoint 2010 PowerShell Script Series Part 1 – Hidden Content Types

I’m excited to kick this series off because I really think PowerShell rocks. The goal of this series is to provide some automation for SharePoint Administrators to perform various deployment and/or troubleshooting tasks. To use the script simply copy it to notepad and save it with a ps1 extension. To run the script on your SharePoint 2010 environment, simply launch PowerShell and get to the directory where the script is located. To run the script type:


The first script was created based on a blog I previously authored here. Please review that blog for more information. The following script provides the following functionality:


Selecting Option 1:

Creates a Content type derived from document and puts it in a special _hidden group at the site level. It also adds the hidden content type to a document library

Selecting Option 2:

If the hidden content type was created previously, choosing option 2 will add the hidden content type

Note: You will need to keep track of the names of the hidden content type by name after they are created.

Write-Host “Press 1 to create a hidden Content Type and add it to a Document Library”
Write-Host “Press 2 to add a previously created hidden Content type to a Document Library”

       write-host “Operation Completed Successfully”

else {write-host “Run the script again and choose option 1 or 2”}
