What Is wsappx and Why Is It Running on My PC?

Basically, wsappx is a Windows process associated with the Microsoft Store (formerly known as the Windows Store) and the Universal Windows Platform (UWP). For those unfamiliar with the Microsoft Store, it’s simply a digital distribution platform created by Microsoft to enable end-users to purchase and download applications. If you have ever owned a Microsoft phone, you may be familiar with the Microsoft Store as the app that lets you download all kinds of paid and free applications.

Wsappx is needed to install, remove, and update Windows Store apps. If you encounter the “wsappx high disk” or “wsappx high CPU” issue, it most likely refers to an error in the process where it constantly runs in the background even if you’re not installing or updating apps from the Windows Store.

Is wsappx a virus?

The simple answer is no. The wsappx process is part of the Windows system and, while it can encounter performance issues from time to time, it is not known to be related to any type of malware or virus.

What causes wsappx to use high disk or high CPU resources on Windows 10?

If you’re experiencing any type of slowdown on your computer, the first course of action to take is to check what’s taking up your CPU usage. To do this, you would have to use Task Manager. Here’s how you can access Task Manager:

  1. Press the Windows key on your keyboard.
  2. Type “Task Manager” on the search box and click the app.

While wsappx is widely regarded as a legitimate Windows process, it is also known to cause both high disk and high CPU usage. Like other Windows tasks and processes, wsappx is also susceptible to errors and issues when trying to manage, install, remove, or update a particular application. As a result, wsappx may take a longer time to complete and may result in higher than normal CPU usage.

Proven methods to fix the “wsappx high disk” or “wsappx high CPU” error

If you expand the wsappx process list on Task Manager, you’ll see sub-processes that are also running in the background:

  • AppX Deployment Service (AppXSVC) – Responsible for the deployment of Windows Microsoft Store applications. There will also be times that you’d notice AppXSVC running while the system tries to update your apps in the background.
  • Client License Service (ClipSVC) – In essence, ClipSVC is a sub-process that provides infrastructure support for the Microsoft Store and ensures that apps downloaded from the Microsoft Store function properly.

Understanding wsappx sub-processes will enable you to determine which type of fix to apply in order to correctly address the issue. If you’re wondering how to fix the wsappx high disk and CPU usage issues, then check out some of the methods we have compiled below.

Method #1: Disable Automatic Updates on the Microsoft Store

To fix the wsappx high CPU issue, the first thing to check is if you have the setting “Update apps automatically” turned on for the Microsoft Store. As mentioned above, the wsappx function generally uses a noticeable amount of CPU usage when your computer is managing apps from the Microsoft Store. If you think this is the main reason why your computer is performing sluggishly, you can opt to disable the automatic updates setting. Here’s how:

  1. Press the Windows key on your keyboard.
  2. Type “Microsoft Store” on the search box and click the app.
