Windows 10: Runaway push notification process using multiple GB of memory on windows 11

In Windows 11 the "Windows Push Notifications User Service 71ace" begins using up multiple gigabytes of memory after running for a few minutes. I can end task the process, but it comes back later or on reboot. I have tried disabling the process by unchecking it in msconfig, but it still starts when I restart the computer.I tried turning it off via services but it doesn't work.

Runaway push notification process using multiple GB of memory

In Windows 10 Home, the "Windows Push Notifications User Service 4e086" begins using up multiple gigabytes of memory after running for a few minutes. I can end task the process, but it comes back later or on reboot. I have tried disabling the process by
unchecking it in msconfig, but it still starts when I restart the computer. I have tried running a clean boot by disabling all non-microsoft services in msconfig and disabling all startup entries in task manager, but the issue still occurs.

I have run virus scan and Malwarebytes anti-malware scan and found nothing. This has been ongoing for multiple weeks.

I'd like to resolve the issue, but if the best I can get is somehow disabling push notifications entirely and stopping that process from ever starting, I would be happy with that too.

 

Runaway push notification process using multiple GB of memory

1. Have been able to get a hint about which App might be running and causing the issue?

Start - Settings - type in --> Notifications

Or Start - Settings - System - Notifcations

See if turning off ALL notifications or even particular ones stop the problem.

Even with "get notificaitons from apps and other senders" and all the other toggles in "notifications & actions" turned off, it still does that.

When I scroll down to "get notifications from these senders" I just get the spinning dots (left it running for several minutes without it displaying any apps).

2. While that is showing Right Click the Taskbar - Task Manager - find it and if there is a little arrow on the left expand it to see what is causing it to run.

The process says "Service Host: Windows Push Notifications User Service_49b3a" and when you click the arrow next to it a sub entry of "Windows Push Notifications User Services_49b3a" shows up.

3. Try Process Explorer while it is running to also see if that help determine cause.

Process Explorer says the hog is svchost.exe using 20,xxx,xxx k private bytes, 9,xxx,xxx k working set and 12.xx cpu.

If needed you can also try a Clean Boot.

No luck with clean boot. Still happens with all non-microsoft services disabled as well as all startup items disabled.

Autoruns

Just installed and ran it. Not really sure what I'm looking for on it that is not in the task manager startup list. Nothing really jumps out as being inappropriate.
