How to Troubleshoot High CPU and Memory Usage By Wsappx in Windows 10 Computers

If your computer is running slow, one way to determine the cause of the problem is to check the Task Manager. Although the task manager displays running processes that may be consuming all the resources, it doesn’t always explain what they mean.

Wsappx is one of those unknown services you see in Task Manager. But even if you see the wsappx process, it’s not really clear what it’s doing. And why does it use a significant portion of your CPU and hard drive resources?

What makes the wsappx use so much CPU and memory?

Many users have complained about the high CPU usage of wsappx. As mentioned in the first paragraph, CPU usage can increase or decrease on its own. But at some point, you will notice high CPU utilization because of this process. Since this process is associated with the Windows Store and/or the Windows Universal App platform, the high CPU load you will see is the result of this process either installing or updating one of the Windows applications.

You will find that you cannot disable this process through Windows services. If you try to do this, you may see a message saying that other applications are affected. The same message (or a variation of it) may also appear when you try to terminate the process via the Task Manager.
