Summary:  Use Windows PowerShell to find information about Windows PowerShell errors.

 How can I find more information about a specific error when I look at the $error automatic variable?

 The $error automatic variable contain rich objects. For example, the InvocationInfo property shows
          what code was called that generated the error.
          The following illustrates how to find the most recent error (error 0):

$Error[0].InvocationInfo

Note  Tab expansion works for this.
