WSAPPX: What Is This Process and Why Does It Use System Resources?

In Windows 10, users may often notice the WSAPPX process, which can sometimes consume a significant amount of CPU and disk resources. This process is linked to the installation, updating, and management of apps from the Microsoft Store.

The Purpose of WSAPPX

WSAPPX includes several services that facilitate the operation of Microsoft Store applications:

  • AppX Deployment Service (AppXSVC): Handles the installation, updating, and removal of apps distributed in the .AppX format.
  • Client License Service (ClipSVC): Manages app licenses and ensures proper functionality of purchased apps.

Why Does WSAPPX Consume High System Resources?

High CPU and disk usage by WSAPPX typically occurs in the following situations:

  • Installing or updating apps from the Microsoft Store.
  • Automatic updates of pre-installed apps, such as "Mail," "Calculator," and others.

Even if you do not actively use apps from the Microsoft Store, the system may update them automatically in the background, which can lead to increased resource usage.

How to Reduce WSAPPX Resource Usage

To minimize the impact of WSAPPX on system performance, you can try the following steps:

  1. Disable Automatic App Updates:
    • Open Microsoft Store.
    • Click the profile icon in the top right corner and go to "Settings."
    • In the "App Updates" section, toggle off "Update apps automatically."
  2. Remove Unnecessary Apps:
    • Go to "Settings" > "Apps" > "Apps & features."
    • Find and uninstall apps you do not use.
  3. Disable Microsoft Store:
    • Open the Local Group Policy Editor by typing gpedit.msc in the Run dialog (Win + R).
    • Navigate to "Computer Configuration" > "Administrative Templates" > "Windows Components" > "Store."
    • Double-click "Disable Store application" and set it to "Enabled."

    Note: Disabling the Microsoft Store may affect the functionality of certain apps, so use this method with caution.
