#Requires -Version 5.1\r\n\r\n<#\r\n.SYNOPSIS\r\n    Sends a toast message\/notification to the currently signed in user.\r\n.DESCRIPTION\r\n    Sends a toast message\/notification to the currently signed in user.\r\n    This defaults to using NinjaOne's logo in the Toast Message, but you can specify any png formatted image from a url.\r\n    You can also specify the \"ApplicationId\" to any string. The default is \"NinjaOne RMM\".\r\n\r\n    Setup Required: Before sending a toast message, this script needs to be ran with just the Setup parameter to prepare the computer.\r\n     This requires running a the SYSTEM user.\r\n\r\n    After Setup: Then the Subject and Message parameters can be used to run the script as the currently signed in user.\r\n\r\n.EXAMPLE\r\n     -Setup\r\n    Sets up the registry with the default settings needed to send toast messages.\r\n    Defaults:\r\n        ApplicationId = \"NinjaOne RMM\"\r\n        ImagePath = \"C:UsersPublicPowerShellToastImage.png\"\r\n        ImageURL = \"http:\/\/www.google.com\/s2\/favicons?sz=128&domain=www.ninjaone.com\"\r\n.EXAMPLE\r\n     -Subject \"My Subject Here\" -Message \"My Message Here\"\r\n    Sends the subject \"My Subject Here\" and message \"My Message Here\" as a Toast message\/notification to the currently signed in user.\r\n.EXAMPLE\r\n     -Setup -ApplicationId \"MyCompany\" -ImageURL \"http:\/\/www.google.com\/s2\/favicons?sz=128&domain=www.ninjaone.com\" -ImagePath \"C:UsersPublicPowerShellToastImage.png\"\r\n    Sets up the registry with the custom setting needed to send toast messages. The example below this is what you will need to use to send the toast message.\r\n.EXAMPLE\r\n     -Subject \"My Subject Here\" -Message \"My Message Here\" -ApplicationId \"MyCompany\"\r\n    Sends the subject \"My Subject Here\" and message \"My Message Here\" as a Toast message\/notification to the currently signed in user.\r\n        ApplicationId: Creates a registry entry for your toasts called \"MyCompany\".\r\n        ImageURL: Downloads a png image for the icon in the toast message\/notification.\r\n        ImagePath: Where the image will be downloaded to that all users will have access to the image.\r\n.OUTPUTS\r\n    None\r\n.NOTES\r\n    If you want to change the defaults then with in the param block.\r\n    ImagePath uses C:UsersPublic as that is accessible by all users.\r\n    If you want to customize the application name to show your company name,\r\n        then look for $ApplicationId and change the content between the double quotes.\r\n\r\n    Minimum OS Architecture Supported: Windows 10\r\n    Release Notes:\r\n    Initial Release\r\nBy using this script, you indicate your acceptance of the following legal terms as well as our Terms of Use at https:\/\/www.ninjaone.com\/terms-of-use.\r\n    Ownership Rights: NinjaOne owns and will continue to own all right, title, and interest in and to the script (including the copyright).
