What is WSAPPX? What Causes It to Increase CPU and Disk Usage in Windows 10

You might have seen an entry called WSAPPX in Task Manager. It is noteworthy for two reasons. First, its unusual name can raise suspicion and secondly, it often consumes a lot CPU and disk resources.

We will explain the WSAPPX process, its purpose, and how to deal with high CPU and disk usage.

What is WSAPPX?

WSAPPX allows you to install, remove, and manage Universal apps via the Microsoft Store on Windows 8 and 10. These Universal/Modern apps were not available on Windows 7 or earlier. You won’t find this process on these Windows versions.

To find it, open the Task Manager by pressing Ctrl Shift + Esc. To expand the Details view, click on the Processes tab. Scroll down to see it.

You can expand the task manager to see two sub-processes. Windows 8 has a sub-process called WSService or Windows Store Service. On Windows 10, you’ll find an identical process called ClipSVC. This is shorthand for Client License Services.

Windows 10 and Windows 8 both include AppXSVC, as well as the AppX Delivery Service.

What does WSAPPX and related processes do?

This may sound complex because of the technical terms, but it is not. According to the Services panel entries, ClipSVC as well as WebService “provide infrastructure support for Microsoft Store.” These processes manage licensing, so if you disable them Store apps won’t function. They are designed to protect against piracy of Microsoft Store apps, if such an issue exists.

To deploy apps, the AppXSVC process is used. It runs every time you update, remove, or install a Store app. Its file extension for Store Apps is AppX. Traditional desktop software runs normally from an executable file ending with EXE.

You can also grab AppX files with the APK extension from any location to sideload Android apps onto your computer. If you aren’t careful, this could expose you to malware.

These sub-processes run under the main WSAPPX program, so you will see an increase in its usage when one of them is active.

Why is WSAPPX using System Resources?

In most cases, WSAPPX will only be active if you are using the Microsoft Store. The process will start by simply opening the file and browsing the site. It will use more resources to download an app or install an update.

This is not a problem with Store apps. Traditional desktop software can also take up resources during its installation. Instead of the WSAPPX process running, the new program will be displayed using your CPU, disk, and other resources.

It’s possible that WSAPPX is still active even though you haven’t used the Microsoft Store or any of its apps. This could be due to the apps being updated in the background. This can be prevented, however.

How to stop automatic updates in store apps

It is simple to disable automatic updates for Store applications. Enter “store” in the Start Menu to open the Microsoft Store Entry. Click the three-dot icon at the top-right and then choose Settings. Toggle the Update Apps slider to off in the Settings menu

This will prevent future app updates from occurring unless you manually trigger them. Click the Menu again to check for updates. Then, choose Downloads & updates. To check for updates, hit the Get Updates button and then install them as needed.

Are there any store apps I need?

Windows 10 can be used without the Microsoft Store. Even if you don’t download anything from Microsoft Store, there are many built-in Windows 10 applications that can be updated through it.

The Xbox app offers a lot of gaming features, including the Calculator, which is now available in the Store. If you don’t have another app installed, the Photos and Mail apps will work fine as defaults, if not. The Store also offers apps like Your Phone that allow you to access the data on your phone right from your computer.

WSAPPX will allow you to see additional usage if any of these are used. We recommend that you disable automatic updates, as they can cause serious damage to your system.

It is difficult for most people to remember to check for updates manually. Because store apps are less restricted than desktop apps, they pose less of a security threat. It’s worthwhile to keep your apps up-to-date, despite the fact that they take up a small amount of time every now and again.

Eliminate Bloatware and Terminate Background Apps

Although we recommend against disabling automatic upgrades, there are still steps you can take to stop Store apps running when you don’t want them to.

The first is to remove bloatware applications from your computer. Windows 10 comes pre-installed junk, such as Candy Crush Saga. These apps are not necessary to be updated in the background.

To view all apps installed on your computer, visit Settings > Applications > Apps & Features. To uninstall an app, click on it and select Uninstall.

After you have deleted the apps that you don’t use, you will only be left with a few apps that you really care about. WSAPPX will not need as many resources if there are fewer apps in the Store.

You should also stop apps running in the background. To toggle this per-app, visit Settings > Privacy>>

Disable an app that is running in the background. It can’t check for notifications or perform any other tasks when it’s not being used. You can disable any apps you don’t use but you should not disable any that you rely on.

To disable background apps completely, you can toggle the Let Apps Run in the Background slider located at the top. However, this is not a viable option.

Can I Stop the WSAPPX Process from Happening?

Windows considers WSAPPX a critical system process. If you attempt to terminate it through the Task Manager, Windows warns that it can cause Windows to become unstable or shut down.

You have no control over when WSAPPX begins and stops. If you browse the Microsoft Store, or interact with apps, it will appear when it is needed and then stop when it is done. You don’t have to manage this process like other system processes. Windows handles processes well by itself, and the steps above should handle any resource-intensive tasks you see in WSAPPX.

WSAPPX is Essential and Simple

This is all you need to know about WSAPPX, and how it uses resources. It is tied to Microsoft Store apps, and runs only when it is needed. If WSAPPX is using a lot of CPU or disk resources, you can uninstall Store apps that you don’t need, stop little-used apps running in the background and disable automatic updates (if you wish to go that far).

You should not worry if WSAPPX is constantly using large amounts of resources.
