Here you will understand WSAPPX. Explore different effective methods to fix WSAPPX High Disk and CPU Usage Issues:

There are a variety of ways to make your computer run faster, but it can be discouraging to discover that your computer is still sucking up a lot of CPU power even when you aren’t running any programs. The Processes which run in the background consume a lot of CPU power.

Both the Windows Store and Microsoft’s Universal app platform use WSAPPX, which is a background process on your Windows 10/8 computer.

This article will focus on this process and the various methods for resolving it.

What is WSAPPX


WSAPPX is a background process that runs in Windows 10, and it manages to download and uninstall files in the system. The program has various processes that look over each process and ensure that these processes are completed with ease.

This program has some major sub-services like AppXSVC, which manages the deployment service, and then it has WS Service, which manages Windows Store, and the last one is ClipSVC which is a Client License Service.

Why does WSAPPX Drain CPU Resources

WSAPPX is a process that runs in your system background due to the presence of applications like Paint and WordPad. The task of WSAPPX involves loading the files in the system and ensuring that the file is downloaded and installed correctly.

If you use Microsoft Store, then you will find this service utilizing the maximum CPU resources in Task Manager.

Some people often confuse WSAPPX as a virus, but it has no malicious code. Rather, it is a genuine Microsoft application. It just uses high CPU resources.

Ways to Fix High CPU Usage

Numerous ways would make it easier for users to fix WSAPPX and high CPU usage.

Method 1: Scan System

The prime cause of high CPU usage in the system is the presence of some malicious code that runs numerous background processes and drains CPU resources. So whenever you face such issues of high CPU usage and system lag, it’s advisable to first restart the system, and if you cannot fix the issue, then run a system scan.

By running a system scan, you can locate malicious and junk files in the system, which are both responsible for a slow system. It’s advisable that you use an advanced system scanner rather than a system default scanner.

When the system runs a check or search, then it goes through all the memory locations, even the ones which are void which results in a time taking process. You need to perform Disk Cleanup to clean such void memory points in the system.
