Fix: WSAPPX High Disk and CPU Usage

If you ever opened the task manager and scrolled to the end, you might have noticed a “WSAPPX” process uses high disk and running in the background. This process runs in the background and responsible for managing the Windows Store and Microsoft’s Universal app platform-related background task.

As soon as you open the Windows Store and install or update apps, this process gets started in the background. Well, it is ok because it gets suspended as soon as the installation is finished. But sometimes you find that the “WSAPPX” process keeps running in the background and causes the high Disk and CPU usages.

You might face problems because this process is already consuming a lot of system resources. Therefore, In this guide, we will walk you through the steps to fix WSAPPX High Disk and CPU Usage.

WSAPPX High Disk and CPU Usage

To control this process, there are a few settings that need to be changed. If you’re installing, uninstalling, or updating store apps, this process will start in the background and keep running until you finish your work.

This process terminates automatically when no apps are updating in the background. Although the “WSAPPX” process uses a small amount of hardware resources, sometimes it starts using a lot of CPU and Disk resources.

Microsoft Store starts updating the apps automatically because you’ve enabled auto apps update service. This may cause high CPU and Disk usage because the WSAPPX process runs in the background.

You can open the store and disable auto apps update option; This will not let the Windows store update the apps automatically in the background.

To do this, run the Store app, and then click the three-dotted icon right next to the profile icon, and select settings. Here, click the toggle “Update apps automatically” button and turn off it.

  6. Select the driver where the Windows operating system is installed.
  7. Next, select the Custom size instead of system managed size.
