What Is Wsappx

Wsappx is a process that runs in the background on your Windows 10/8 computer as a part of the Windows Store and the Universal app platform of Microsoft.

Mostly, wsappx includes two separate background services - AppX Deployment Service (AppXSVC) and Client License Service (ClipSVC) on Windows 10. If you are using Windows 8, you will see AppXSVC and WSService (Windows Store Service).

Wsappx is used for installations, updates, and uninstallation of Store apps, so once you are done installing all updates, you don't need it.
