As part of iOS development, Apple offers a framework known as UserNotifications. This framework enables local and remote notifications to be delivered and handled. For example, I get notifications an hour before I tutor a student about when to leave for an appointment, and I also get these from the New York Times about important news articles.

As part of an audit I did recently on my PC to ensure that I wasn’t sending any telemetry data to Microsoft that I wasn’t comfortable with (and that’s easy to do in Windows by the way, it doesn’t require a third party tool) I came across Windows Push Notifications, they’re part of the Windows Notification Service (WNS). I spotted WNS when running Wireshark to check what telemetry packets were being sent to Microsoft, there was a persistent connection that sent and received encrypted data to IP address – this is the current IP address of the host A data packet exchange was occurring every minute. Yep, ever single minute of every single day my (and your) PC does an encrypted data exchange with a Microsoft WNS server. What’s going on here?

The push notification service helps users get notifications on their mobile devices. You define them in Application Composer, using conditional logic to determine if there is a need for a notification. Devices such as iOS and Android support push notifications.

Windows Push Notification User Service

Using the Windows 10 operating system, you can receive notification messages from the Push Notification User Service. In the absence of this platform, users cannot receive notifications from the operating system they have installed because it supports local or push notifications.

When student loan forgiveness applications opened in 2022, the FBI warned borrowers to watch out for scams targeting applicants. Student loan forgiveness scammers may contact you via phone or create phony application sites aimed at stealing your Social Security number or your bank account information. They may put pressure on their victims with fake urgent messages that encourage you to apply for debt relief before it’s too late. Then they’ll charge you a hefty application fee. In reality, it’s a scam.

Apns Stands For

Apple Push Notification service (commonly referred to as Apple Notification Service or APNs) is a platform notification service created by Apple Inc. that enables third party application developers to send notification data to applications installed on Apple devices. The notification information sent can include badges, sounds, newsstand updates, or custom text alerts. It was first launched with iOS 3 on June 17, 2009. APNs support for local applications was later added to the Mac OS X API beginning with the release of Mac OS X 10.7 (“Lion”). Support for website notifications was later added with the release of Mac OS X 10.9 (“Mavericks”).

Hi all, we’re currently experiencing an issue with routing incoming calls to iOS and Android devices.
Incoming calls are delivered to the web and desktop apps, though with a small delay.
On iOS and Android, you’ll receive a “Missed call” notification so you will be able to tell who is trying to reach you.
Being able to place calls isn’t impacted so you should be able to make outgoing calls without issues.
We’re working with our partners on restoring the routing of incoming calls to mobile apps as soon as possible and will keep you posted as soon as we have an update.
Sorry for the inconvenience and thanks for your patience!

It provides local or push notifications for Windows 10 users through the Windows Push Notification User Service (WpnUserService). This notification service can sometimes stop working and you can’t receive notifications.

Push notifications were only available (for me) by using the following menu in Visual Studio: Set the app identity automatically:

Windows Push Notifications User Service has stopped unexpectedly. You will usually receive an error message that indicates the service stopped working.

Below are some solutions you can try if your Windows Push Notifications custom service is not responding.

Apple Push Notifications Service

Your app can display notifications, play a sound, or update an icon badge by using local or push notifications. Notifications can display messages, play sounds, or display the time and location of your app.


Why does the Windows Push Notification user service stop working?

Why does the Windows Push Notification user service stop working?

Be sure to check out the most common causes of this problem, so you can determine what is causing it and solve it quickly.

Memory leak caused by the service: Large memory leaks occur due to missing or corrupt system files used by the service. Be sure to replace these files with an SFC scanner.

How Apns Works

Apple Push Notification service (APNs) propagates push notifications to devices having applications registered to receive those notifications. Each device establishes an accredited and encrypted IP connection with the service and receives notifications over this persistent connection. Providers connect with APNs through a persistent and secure channel while monitoring incoming data intended for their client applications. When new data for an application arrives, the provider prepares and sends a notification through the channel to APNs, which pushes the notification to the target device..

Notification database corrupted: The notification database is a file that resides on your computer and can be corrupted, causing the service to lock up. Users have reported that deleting this file causes Windows to recreate it, which fixes the problem.

Do not disturb the Avast Antivirus component: The Avast Antivirus component does not allow users to receive notifications but also causes this problem when it is not enabled. Make sure that it is removed.

Send Notification

If your users are not visiting your website, you can send them push messages to keep them informed.

Occasionally, the Windows 10 software could have a bug. If this happens, you should update all Microsoft applications on your computer. To do this, go to Settings > Update & security > Windows Update. Select Check for an update or Install now.

There is another service called Windows Push Notification System Service which you can stop and disable and that apparently disconnects the PC from the WNS server. It does seem to work too, the one minute packet exchange stops when yous top (and disable) this service. Experimenting has shown that if you set it to Manual (which is the wiser option when ‘disabling’ services) it gets restarted. If you disable this service all your push notifications will stop and UWP apps will no longer receive updates and badges etc.
