The wsappx process is related to Windows Universal Apps (WUA) and Windows Store and runs in the background. Double-clicking the wsappx process will reveal two additional sub-processes running under wsappx: AppXSVC and ClipSVC. AppXSVC provides infrastructure support for deploying Store applications, while ClipSVC provides infrastructure support for Microsoft Store.

You may have noticed that the wsappx process consumes a significant percentage of CPU processing power when installing, uninstalling, or automatically updating Microsoft Store apps.

This is a normal operation of the process, and you should not need to take any action. However, this service may be having issues trying to install, uninstall, or update an app - this might cause higher than normal CPU usage over an extended period.

The guide below describes how to fix potential problems related to the wsappx process and high CPU usage.

Disable Windows Store Using Local Group Policy Editor

The Local Group Policy Editor (also known as gpedit.msc) is a Microsoft Management Console that allows users to manage Computer Configuration and User Configuration settings.

This feature is available only in Windows Pro, Enterprise, and Education editions, not others like Windows Home Edition. If your operating system supports this feature, you can use it to disable Windows Store.

To open Local Group Policy Editor, launch Run, type "gpedit.msc", and press Enter to start it. Now follow this path: "Computer Configuration > Administartive Templates > Windows Components > Store". In the Store folder, you will see several settings, one of which is named "Turn off the Store application". Double-click it, choose the "Enabled" option and click "Apply" to save the changes and disable Windows Store.

If you want to undo these changes, simply set "Turn off the Store application" setting to "Disabled".

NOTE: Third-party apps cannot be installed or updated when Windows Store is disabled.
