What is WSAPPX and how to fix high CPU usage?

Issue: Hello. I recently updated my Windows 10 with the latest updates and noticed that it is working kind of slow. When I opened the task manager, I noticed that the process wsappx is taking nearly 90% of my CPU usage!

Issue: When I clicked on it, it showed the AppX Deployment Service (AppXSVC) service and WSAPPX. What is it, and can I shut it down? If not, how can I fix AppX Deployment Service (AppXSVC) service high CPU usage? Any help would be appreciated.

Wsappx is a process that you can find running in the background (Task Manager) at any time when your Windows 10 or Windows 8/8.1 machine is turned on. It is an important part of the operating system and is responsible for installing, uninstalling, and updating Microsoft Store applications. Nevertheless, it is not needed when all of the mentioned operations are not in use.

AppX Deployment Service (AppXSVC) is of the services[1] that you can find running under the wsappx process in the Task Manager. If you are running Windows 8, you might also see Windows Store Service (WSService), while on Windows 10 you will encounter Client License Service (ClipSVC).
