ToastNotifications sent from PowerShell disappear from Action Center

Question

I'm using this code to send notifications from PowerShell script. PowerShell itself is launched by (persistent) Java application.

[Windows.UI.Notifications.ToastNotificationManager, Windows.UI.Notifications, ContentType = WindowsRuntime] > $null
[Windows.Data.Xml.Dom.XmlDocument, Windows.Data.Xml.Dom.XmlDocument, ContentType = WindowsRuntime] > $null
[Windows.UI.Notifications.ToastNotification, Windows.UI.Notifications, ContentType = WindowsRuntime] > $null
$xml = New-Object Windows.Data.Xml.Dom.XmlDocument
$template = "<toast><visual><binding template=`"ToastText02`"><text id=`"1`">Title</text><text id=`"2`">Test results</text></binding></visual></toast>"
$xml.LoadXml($template)
$toast = New-Object Windows.UI.Notifications.ToastNotification $xml
[Windows.UI.Notifications.ToastNotificationManager]::CreateToastNotifier("sbt").Show($toast)

They pop up on the screen and are visible in Action Center for while but quickly disappear. Notifications sent by the XAML app with the same code stay there for quite some time. Is there a way to change behavior of notifications sent via script?

Answer 1

You must set a registry key for each AppID whose notifications you would like to persist in the Action Center.

For example, if you want your irssi notifications to persist, add the key: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Notifications\Settings\irssi with a DWORD named ShowInActionCenter with value 1.

Thanks to "Passing By" for the solution in this article's comments, and Mattias Fors for creating the article.

Update: You can also toggle this in your "Notifications & actions" Settings on a per-app basis.
