WSAPPX is the background process associated with the Microsoft Windows Store and Universal App Platform, which tries to run always in the background and may cause a high amount of disk and CPU usage sometimes. You may notice 100% CPU usage error message in some cases as well. WSAPPX is basically used for the automatic checking of installation and uninstallation of Windows Store apps. It’s of no use while all the app updates from the Windows Store are installed or while all the apps are up-to-date in your Windows 10 system. The user having the low to medium hardware resource for running the Windows 10 OS may face trouble while WSAPPX runs in the background. It certainly takes a high amount of CPU and disk resource while actually, it is of no use.
There are few ways to eliminate the WSAPPX process from running in the background. Thus, a general PC user saves the high amount of usage of unwanted background processes. It saves a certain amount of RAM from being used and improves the overall performance of a computer. You may perform a CPU stress test to know the actual performance of your PC.
