It looks like controlled by Windows itself.

That's different.

@Mygod please develop. What is different?

[celeron533]

@florianmonfort , it is different from the screenshot I have posted. At first I was thinking it was just a balloon notification.

But there may have some limitations when using the Toast Notification:

Sending toast notifications from desktop apps

Generally, sending a toast notification from a desktop app is the same as sending it from a Windows Store app. However, you should be aware of these differences and requirements:

• For a desktop app to display a toast, the app must have a shortcut on the Start screen.
• The shortcut must have an AppUserModelID.
• Desktop apps cannot schedule a toast.

Have to keep compatibility with the older operating systems.
You can always get notified with version checking enabled, miss it once is not a big problem.
