.Synopsis
    Generates the Office Deployment Tool (ODT) Configuration XML from the current configuration of the target computer

.DESCRIPTION
    This function will query the local or a remote computer and Generate the ODT configuration xml based on the local Office install
    and the local languages that are used on the local computer.  If Office isn't installed then it will utilize a DefaultConfiguration file

.PARAMETER ComputerName
    The computer or list of computers from which to query

.PARAMETER Languages
    Will expand the output to include all installed Office products

.PARAMETER TargetFilePath
    The path and file name of the file to save the Configuration xml

.PARAMETER IncludeUpdatePathAsSourcePath
    If this parameter is set to $true then the SourcePath in the Configuration xml will be set to 
    the current UpdatePath on the local computer.  This assumes that the UpdatePath location has 
    the required files needed to run the installation.
     
.PARAMETER DefaultConfigurationXml
    This parameter sets the path to the Default Configuration XML file.  If Office is not installed on
    the computer that this script is run against it will default to this file in order to generate the 
    ODT Configuration XML.  The default file should have the products that you would want installed on 
    a workstation if Office isn't currently installed.  If this parameter is set to $NULL then it will
    not generate configuration XML if Office is not installed.  By default the script looks for a file
    called "DefaultConfiguration.xml" in the same directory as the script.

.EXAMPLE
    Generate-ODTConfigurationXml | fl

    Will generate the Office Deployment Tool (ODT) configuration XML based on the local computer

.EXAMPLE
    Generate-ODTConfigurationXml  -ComputerName client01,client02 | fl

    Will generate the Office Deployment Tool (ODT) configuration XML based on the configuration of the remote computers client01 and client02

.EXAMPLE
    Generate-ODTConfigurationXml -Languages OSandUserLanguages
    
    Will generate the Office Deployment Tool (ODT) configuration XML based on the local computer and add the languages that the Operating System and the local users
    are currently using.

.EXAMPLE
    Generate-ODTConfigurationXml -Languages OSLanguage
    
    Will generate the Office Deployment Tool (ODT) configuration XML based on the local computer and add the Current UI Culture language of the Operating System

.EXAMPLE
    Generate-ODTConfigurationXml -Languages CurrentOfficeLanguages
    
    Will generate the Office Deployment Tool (ODT) configuration XML based on the local computer and add only add the Languages currently in use by the current Office installation

Function Set-ODTConfigProperties{
<#
.SYNOPSIS
    Modifies an existing configuration xml file to set property values

.PARAMETER AutoActivate
    If AUTOACTIVATE is set to 1, the specified products will attempt to activate automatically. 
    If AUTOACTIVATE is not set, the user may see the Activation Wizard UI.
    You must not set AUTOACTIVATE for Office 365 Click-to-Run products. 

.PARAMETER ForceAppShutDown
    An installation or removal action may be blocked if Office applications are running. 
    Normally, such cases would start a process killer UI. Administrators can set 
    FORCEAPPSHUTDOWN value to TRUE to prevent dependence on user interaction. When 
    FORCEAPPSHUTDOWN is set to TRUE, any applications that block the action will be shut 
    down. Data loss may occur. When FORCEAPPSHUTDOWN is set to FALSE (default), the 
    action may fail if Office applications are running.

.PARAMETER PackageGUID
    Optional. By default, all Office 2013 App-V packages created by using the Office 
    Deployment Tool share the same App-V Package ID. Administrators can use PACKAGEGUID 
    to specify a different Package ID. Also, PACKAGEGUID needs to be at least 25 
    characters in length and be separated into 5 sections, with each section separated by 
    a dash. The sections need to have the following number of characters: 8, 4, 4, 4, and 12. 

.PARAMETER SharedComputerLicensing
    Optional. Set SharedComputerLicensing to 1 if you deploy Office 365 ProPlus to shared 
    computers by using Remote Desktop Services.

.PARAMETER TargetFilePath
    Full file path for the file to be modified and be output to.

.PARAMETER PinIconsToTaskbar
    Optional. Set PinIconsToTaskbar to $true to pin icons to taskbar and $false to not.  Does not apply to Windows 10

.Example
    Set-ODTConfigProperties -AutoActivate "1" -TargetFilePath "$env:Public/Documents/config.xml"
    
    Sets config to automatically activate the products

.Example
    Set-ODTConfigProperties -ForceAppShutDown "True" -PackageGUID "12345678-ABCD-1234-ABCD-1234567890AB" -TargetFilePath "$env:Public/Documents/config.xml"
    
    Sets the config so that apps are forced to shutdown during install and the package guid
    to "12345678-ABCD-1234-ABCD-1234567890AB"

.Notes
    Here is what the portion of configuration file looks like when modified by this function:

    <Configuration>
      ...
      <Property Name="AUTOACTIVATE" Value="1" />
      <Property Name="FORCEAPPSHUTDOWN" Value="TRUE" />
      <Property Name="PACKAGEGUID" Value="12345678-ABCD-1234-ABCD-1234567890AB" />
      <Property Name="SharedComputerLicensing" Value="0" />
      <Property Name="PinIconsToTaskbar" Value="1" />
      ...
    </Configuration>
