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

Most often, wsappx consists of two separate background services – AppX Deployment Service (AppXSVC) and Client License Service (ClipSVC) in Windows 10. If you are using Windows 8, you will see AppXSVC and WSService (Windows Store Service).

Wsappx is used to install, update, and uninstall Store apps, so you won’t need them anymore after you install all the updates.

What makes the wsappx use a lot of CPU and memory?

In Windows 10, the wsappx process has sub-processes known as Client License Service or ClipSVC and AppX Deployment Service or AppXSVC.

The ClipSVC service handles licensing and piracy protection for apps in the Store, and the AppXSVC service deploys apps, so it runs every time you install, update, or uninstall an app. So if you disable any of these services, the apps in the Store stop working.

If the sub-processes are active and running, the load on the wsappx process increases. Although wsappx is an important system process, it should not be on all the time. It is only needed when you want to install, update, or uninstall apps from the store.
