What is WSAPPX?
WSAPPX Windows 10 is a background service in Windows 8/10. Part of Windows Store, this program communicates with the Windows Store to update Windows apps.
When this service becomes unresponsive, it starts consuming a lot of memory on your CPU. As a result, your PC will slow down, giving you huge lag time. It could easily disturb system performance.
Why Is It Using So Much CPU?
The wsappx service generally uses a noticeable amount of CPU when your PC is installing, uninstalling, or updating Store apps.
So, if you are noticing WSAPPX disk usage taking 100% disk usage, it could be due to an app installing in the background.
To see whether this service is currently installing/updating an app, simply open Windows Store. Click on the user icon from the right top corner. On the next window, you can easily disable automatic app updates.
Is It a Virus?
The wsappx software is a part of Windows 10 itself. We haven’t seen any reports of malware disguising itself as the wsappx, AppXSVC, or wsappx disk usage.
However, if you’re concerned about malware, it’s always a good idea to run a scan with your preferred antivirus program to check your system for anything dangerous.
