3 Ways to Fix WSAPPX High Disk and CPU Usage on PCs

No one likes it when their PC is running very slow, or the processor heats up excessively. But somehow, these things happen, and they are typically caused due to too many processes running in the background. Windows OS is the most popular computer OS used by many of us; it is more intuitive and highly customizable.

Well, one of the processes that make your PC sluggish is WSAPPX. This background process utilizes more system resources; thus, causing your PC to run slowly. However, in today’s article, we’d explain how you can stop this background process from affecting your system’s process. But before then, what is WSAPPX?

What is WSAPPX?

WSAPPX is a Windows OS background process that actively runs on all Windows OS computers by default. Well, this process is quite important; it handles installation, uninstallation, and managing of apps through the Microsoft Store. This process is important for Microsoft Windows Store and Universal Windows Platform (UWP) to run smoothly.

It is only advisable to disable or stop this process after you must have updated or installed all the apps you need to get from the Microsoft Store. Disabling this process would free up more memory; thus, allowing your PC to run much better and faster than ever.

However, if you can find it, and discover that it is among the processes with high CPU and disk usage, then you need to disable it. Well, disabling this process won’t stop your PC from running, and it can speed up your system’s performance.
