Version 1.2 - 09/01/21
Added logic so if the script is deployed as SYSTEM it will create a scheduled task to run the script for the current logged on user.

Version 1.1 - 30/12/20
Added Snooze Switch option
Version 1.0 - 22/07/20
Release
.SYNOPSIS
The purpose of the script is to create simple Toast Notifications in Windows 10
.DESCRIPTION
Toast_Notify.ps1 will read an XML file so Toast Notifications can be changed "on the fly" without having to repackage an application. The CustomMessage.xml file can be hosted on a fileshare.
To create a custom XML, copy CustomMessage.xml and edit the text you want to disaply in the toast notification. The following files should be present in the Script Directory
Toast_Notify.ps1
BadgeImage.jpg
HeroImage.jpg
CustomMessage.xml
.PARAMETER XMLScriptDirSource
Specify the name of the XML file to read. The XML file must exist in the same directory as Toast_Notify.ps1. If no parameter is passed, it is assumed the XML file is called CustomMessage.xml.
.PARAMETER XMLOtherSource
Specify the location of the Custom XML file used for the Toast when it is not in the same directory as the Toast_Notify.ps1 script
.PARAMETER Snooze
Add a snooze option to the Toast
.EXAMPLE
Toast_Notify.ps1 -XMLOtherSource "\\fileserverhome\xml\CustomMessage.xml"
.EXAMPLE
Toast_Notify.ps1 -XMLSciptDirSource "PhoneSystemProblems.xml"
.EXAMPLE
Toast_Notify.ps1 -Snooze
