Its always handy to ask the User to reboot once the install has finished, here is a simple TOAST message with Image (445 x 266) to add to the end of the deployment...
Edit the following Powershell with the message, image location etc
copy-Item "***Path To Images***\images\reboot.png" -Destination "C:\temp"
Start-Sleep -Seconds 3
$app = '{1AC14E77-02E7-4E5D-B744-2EB1AE5198B7}\WindowsPowerShell\v1.0\powershell.exe'
[Windows.UI.Notifications.ToastNotificationManager, Windows.UI.Notifications, ContentType = WindowsRuntime]
$Template = [Windows.UI.Notifications.ToastTemplateType]::ToastImageAndText01
#Gets the Template XML so we can manipulate the values
[xml]$ToastTemplate = ([Windows.UI.Notifications.ToastNotificationManager]::GetTemplateContent($Template).GetXml())
[xml]$ToastTemplate = @"
