.SYNOPSIS
Retrieves the Windows AutoPilot deployment details from one or more computers
.DESCRIPTION
This script uses WMI to retrieve properties needed by the Microsoft Store for Business to support Windows AutoPilot deployment.
.PARAMETER Name
The names of the computers.  These can be provided via the pipeline (property name Name or one of the available aliases, DNSHostName, ComputerName, and Computer).
.PARAMETER OutputFile
The name of the CSV file to be created with the details for the computers.  If not specified, the details will be returned to the PowerShell
pipeline.
.PARAMETER Append
Switch to specify that new computer details should be appended to the specified output file, instead of overwriting the existing file.
.PARAMETER Credential
Credentials that should be used when connecting to a remote computer (not supported when gathering details from the local computer).
.PARAMETER Partner
Switch to specify that the created CSV file should use the schema for Partner Center (using serial number, make, and model).
.EXAMPLE
