What is WSAPPX?

WSAPPX is an important background process in Windows 8 and Windows 10 Operating Systems. Microsoft Universal App platform and Windows Store relies on WSAPPX. The main job of WSAPPX is to operate, install, uninstall or delete the Store apps. It communicates with the Store to keep the Windows apps updated. However, this may lead to the high disk, memory or CPU usage problems at times. When WSAPPX is consuming a lot of CPU resources, you’ll see the processes like wsappx (3) and wsappx (2) in the task manager. When WSAPPX process becomes unresponsive, it leads to high CPU usage problems, computers starts lagging and this is what irritates us a lot. Well, here are the well researched and tested solutions to stop High CPU and High Disk Usage by WSAPPX Services or Tasks.


What is WSAPPX?

Why WSAPPX Uses High CPU?

When you open Windows Task Manager, you see a list of over dozen processes under the Processes tab. WSAPPX is one among them. It usually appears as svchost.exe wsappx, wsappx(2) or wsappx(3). WSAPPX process will be started when you just open and browse the Microsoft Store. It goes active when you are installing an update or downloading an application. If you expand the wsappx(3) selection, you’ll see the sub-processes like Client License Service (ClipSVC), Windows Store Service (WSService) and AppX Deployment Service (AppXSVC).

Client License Service (ClipSVC)

It is the service which provides CPU infrastructure support for the Microsoft Store. It gets initiated when the disabled apps bought from Microsoft Windows Store works in a wrong way. This service is available only on Windows 10 OS.

Windows Store Service (WSService)

It serves the same purpose as Client License Service (ClipSVC). It is there in Windows 8 OS also. If you disable any of these sub-processes, the apps you’ve downloaded from Windows Store will not work. These processes are created to safeguard the Windows Stores applications against piracy.

AppX Deployment Service (AppXSVC)

This process helps to deploy the Windows Store apps. So, it runs whenever you uninstall, installs or update any of the Store applications. AppX is the file extension of all the Windows Store apps.

All these processes consume a lot of CPU resources when you download, install or update the apps from Windows Store. If you do not use the Store and you see WSAPPX is using abnormal CPU, it means that the applications are automatically updating. Fortunately, this issue can be easily fixed!
