What is Wsappx?
Wsappx is usually considered as a virus due to high disk usage. But It’s a window store Program that searches your computer for Installed Apps and extracts their information to send them to Microsoft. If you expand this program you will find three more services that are listed below:Windows Store Service (WSService),
Client License Service (ClipSVC)
AppX Deployment Service (AppXSVC).
AppX Deployment Service (AppXSVC)
This service provides infrastructure support for deploying Store applications. It is started on demand and if disabled Windows Store applications will not be deployed to the system, and may not work correctly.
Client License Service (ClipSVC) and Windows Store Service (WSService)
These Services supply infrastructure support for the Microsoft Store. This service is started on demand and if disabled applications bought using Windows Store will not function correctly.
