Windows 10: AppX Deployment Service AppXSVC High CPU Usage

Hi,I've been having issues lately where a windows service under the name of Wsappx and AppX Deployment Service have been using a high percentage of my CPU for no understandable reason. It is consistently like this from start up of the PC to shutdown. I have tried multiple solutions seen on the forums in the past and yet I've gotten nothing to alleviate the CPU usage. It is consistently taking up about 20% of my CPU and makes the temps sit at a consistent 60 degrees and around 50% CPU usage at idle.Here are some of the solutions I have tried so far:Restarting my deviceShutting down the service

AppX Deployment Service (AppXSVC) runs at Startup. Is this normal?

I have not concentrated on this issue before. But I noticed that on my dads Windows 8.1 machine AppX Deployment Service (AppXSVC) will not startup during Windows boot, yet under Windows 10 this will always start even when set to Manual.

I have Windows 10 1903 64-bit Pro. I have uninstalled and turned off live tiles as well as turning off background apps for all of the store apps. I also disabled the Store app and also tried enabling it as well. The Store app is not running in the background.

However, I have noticed AppX Deployment Service (AppXSVC) start up always when the PC starts up. For the benefit of the doubt I have even updated all the Windows store apps successfully without issues.



So as you can see there is no data usage for my store apps.

The question is why and is it normal? Also when I go to File Explorer and then click on the Video, Pictures, etc folder then this service will start up! If this AppXSVC is associated with the Store app then why does this start when I click on videos folder for example when I already have VLC as the default player? If the videos and pictures have nothing to do with any of the store apps then I don't understand why AppXSVC triggers to run.

I just updated Windows 10 a couple of hours ago to the latest Windows 10 1903(OS build 18362.720) from Version 1903 (OS Build 18362.329) that I had 7 months ago. This made no difference whatsoever.

Can someone reassure me if this behaviour is normal? Is it meant to really start-up?

Apologies for the delayed response. I have just conducted this experiment by disabling AppXSVC manually using regedit by setting Start value to 4 and I do not experience those crashes that you are describing following the PC restart!





Are you sure that this service is really important for the other Windows internal features other than the deployment of the store apps? I don't use store apps and even if I do I can always re-enable manually.

Still I have yet to find out if it is really normal for this service to start by itself. It periodically stops, I know. But what is triggering it to start is making me really confused. I can see it does get triggered in File Explorer, particularly when viewing the Videos folder.

This is something I really do not understand. I'm the only one at home that uses Windows 10 so I don't have any other references for test purpose other than my dads Windows 8.1 system where AppXSVC does not get triggered in any of these scenarios.

I think your crashing is related to something else, not the AppXSVC Deployment Service because I don't get crashes or error messages with this service disabled.

 

High CPU Usage at Idle

Hi, wsappax is related to Store apps (universal apps).

I'm wondering why explorer is using so much CPU time.

System and Compressed memory should normally be using negligible CPU time.

Presumably Defender (Antimalware) is active 'cos of other activity.

2-3% CPU use in Safe Mode is high... can you post a screenshot of your task manager in Safe Mode?

wsappax:
If you expand the selection, one, two or even three Windows services are listed: Windows Store Service (WSService), Client License Service (ClipSVC) and AppX Deployment Service (AppXSVC).

AppX Deployment Service (AppXSVC)
Provides infrastructure support for deploying Store applications. This service is started on demand and if disabled Store applications will not be deployed to the system, and may not function properly.

Client License Service (ClipSVC)
Provides infrastructure support for the Microsoft Store. This service is started on demand and if disabled applications bought using Windows Store will not behave correctly.

Windows Store Service (WSService)
Provides infrastructure support for Windows Store. This service is started on demand and if disabled applications bought using Windows Store will not behave correctly.

====================================
You have 0 internet activity, so this is nothing to do with app updates.
A quick search on wsappx and CPU use does not suggest an immediate solution. I've found nothing on this forum on wsappx.

Have you recently installed any new apps since this became apparent?
Do you have a system restore point created before this started, or a disk image you can revert to?
(We strongly and repeatedly recommend disk imaging e.g. Macrium reflect (free) + its boot medium + external storage).

Can you try a clean boot, then post a screenshot of your task manager?
