So the other day, my desktop suddenly started lagging for no apparent reason. I checked the task manager and saw that “Service Host: Windows Push Notifications User Service” had the highest RAM usage. The worst part was the memory usage was continuously increasing and it was using multiple gigabytes of memory.
I tried to end the service, but it started again after some time. First I thought it was malware, then I tried the malware removal guide to scan for malware and viruses, but no luck.
I tried almost every solution available on the internet but still no luck. I was almost going to reset my PC then I finally found a solution which actually worked.

Issue: Hello. I noticed in Task Manager that the Windows Push Notifications User Service uses about 20% or 30% of CPU and RAM. What should I do?
Solved Answer
High CPU[1] or memory usage in Windows can occasionally be caused by the Windows Push Notifications User Service, a background system process that manages push notifications from different apps and services. Many users have experienced this problem, which can be very annoying because it affects the responsiveness and functionality of the system.
Although it doesn’t happen frequently, one user noticed that it seems to happen more often after they have been in full-screen mode. Although the precise cause of this behavior may not always be known, it appears that specific circumstances or actions are what cause the high CPU or memory consumption that is related to this service. This finding could point to a possible relationship between the graphics or display settings in full-screen apps and the Windows Push Notifications User Service.
The effects of this problem on users may be profound. Applications that are unresponsive and slow system performance can be caused by high CPU or memory use. Additionally, it may impair multitasking abilities, making it difficult for users to efficiently use other applications. Furthermore, excessive use of system resources can shorten the lifespan of computer components by causing overheating.

Updating Windows and the impacted apps is an additional strategy to make sure that any known problems are fixed. These kinds of issues are occasionally fixed by system updates.

Windows Push Notifications User Service Issue — Process Maxes Out CPU and Memory
After updating Windows 10 today, I’ve run into a strange issue: a single process, Windows Push Notifications User Service, will regularly start and then slowly use nearly all my available CPU and Memory until either I end the process or the computer ceases to function. When I end the process, it is dormant for a while but always restarts again and goes through the same cycle of using up all available CPU and Memory.
From what I can tell, the issue is not with any particular app trying to send a push notification but rather with the Windows Push Notification Service itself. I have all notifications turned off; however, I find that the process always starts up when I got to the Notification Settings tab. When I do that, no apps are shown under «Get notifications from these senders» nor are any of the lower down options shown either; instead, I just get the loading circular dots animation under «Get notifications from these senders» while the Windows Push Notifications process slowly uses up all available CPU and Memory. When I forcibly end the task using the Task Manager, the loading dots are replaced by the following text: «No senders have provided notifications yet.»
Does anyone know how to prevent this from happening? I spoke with Windows technical support but they were unable to fix the problem — nearly as soon as I got off the phone with them (thinking the issue was fixed), it happened again. Any help would be greatly appreciated.

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.

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.
