Do you use Nintex workflows in your SharePoint environment? Have a look-see for this upload in Codeplex: Execute PowerShell Script Nintex Workflow Action

The “Execute PowerShell Script” action allows you to execute PowerShell scripts from within Nintex Workflow 2010 workflows. This is a custom Nintex workflow action based on Christian Glessners’ Execute PowerShell Script Action (part of his  Advanced Workflow Actions for SharePoint Designer 2010) which you can find also in CodePlex.

Be sure to investigate two other major workflow players for SharePoint: AgilePoint and K2.
