Why Wsappx Causes High CPU Usage and How To Fix It.
If your computer is running slowly, one way to figure out the cause of the problem is to check your Task Manager. The Task Manager displays running processes that may take up all resources but does not necessarily explain what they mean.
Wsappx is one of those unfamiliar services that you will see in Task Manager However, even if you see the wsappx process, it is not entirely clear what it is doing. And why does it take up a significant chunk of CPU and disk resources?
This article will show you why wsappx is causing the high CPU usage and how to fix it.
What is Wsappx?
Wsappx is a legitimate Windows service that is known to cause high utilization of both disk and CPU. The service that handles the Microsoft Store (formerly Windows Store) and the Universal App Platform runs continuously. However, the number of resources used can be minimal or significantly more depending on what you are doing.
For example, if you install a Microsoft Store app or PC software outside of the Store, the wsappx process will use more CPU or disk resources. The same happens when you launch, update, or uninstall the application.
Why Wsappx is causing high CPU usage
On Windows 10, the wsappx process has sub-processes known as the CAL or ClipSVC service and the AppX or AppXSVC deployment service
The ClipSVC service handles licensing and piracy protection for Store apps, while AppXSVC deploys apps, so it runs every time you install, update, or uninstall an app. Thus, if you disable any of these services, Store apps will not work.
When the subprocesses are up and running, you will see the wsappx process usage increase. Although wsappx is a vital system process, it doesn’t have to be enabled all the time. It is only needed when you want to install, update or remove apps from the Store.
Note. If you are using a Microsoft Store app and receive a licensing error, you need to enable ClipSVC and AppXSVC services.
What to do when Wsappx is causing high CPU usage
If you see wsappx is using a significant portion of your CPU, there are several fixes to fix the problem.
Run a virus scan
If you have a virus or malware on your computer, it can cause spikes in the use of various Windows processes. The same is true if any downloaded apps or Microsoft Store apps are infected.

Note. We do not recommend disabling Windows Store if you need frequent automatic updates for applications such as Photos, Calculator, Mail, Movies & TV, and OneNote. Also, you cannot install or update third-party Windows Store apps when Windows Store is disabled.
Disable automatic updates for Store apps
