Windows 10: Windows freezes due to runaway push notification process using nearly all memory

The Microsoft Store app is likely to consume high levels of computer memory if the account is signed in. This may be observed in a task manager process such as Service Host: Windows Push Notifications User Service, which may be associated with the WpnUserService. The solution is to 1 sign out of the Microsoft Store app then 2 run SFC /SCANNOW then 3 restart the computer. There has been consistent success using these steps.

Windows Push Notification User

Glad to hear it. Keep us posted.

Runaway memory usage

CPU usage graph is still nasty:



And the process list still shows AVGSvc at 13%, and explorer at 13%.

 

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.
