Have you noticed a Windows service named WSAPPX using most of your CPU resources in the task manager?

WSAPPX High CPU Usage Error

You are not alone. A lot of people have been wondering what this high disk usage error is.

In this post, we’ll walk you through the steps of fixing the issue.

What is WSAPPX?

WSAPPX is service in Windows 10/8 that runs on your PC as part of the Windows Store and Microsoft’s Universal app platform.

It is used to install, update and uninstall Store apps, so you might not need it after installing all your updates. But sometimes this service can become unresponsive and start consuming most of your CPU resources.

As a result, your PC becomes slow and you experience a huge lag time.

Why Is It Consuming Most of Your CPU Resources?

Generally, WSAPPX uses noticeable amounts of CPU when updating, installing, or uninstalling Store apps.

This means if you notice the Windows service consuming a high percentage of your CPU resources, it could be because an app is installing or updating in the background.

To see this action, go to the Windows Store and click on the user icon on the top-right corner. You can disable automatic app updates on the next window.

How to Fix It

You might have noticed that it’s not possible to disable this service in Windows Services.

If you try to disable it, you will see a message saying this action will affect other apps. You may also see a similar message if you try to end the service in Task Manager.

But there are ways to disable this service. If you don’t use Windows Apps regularly or you simply want to solve the high CPU usage error, there a few things you can do.

We have covered simple fixes that will help you to solve this problem and get your PC running smoothly again.

Using Registry Editor

Unfortunately, some Windows versions don’t have the Group Policy Editor. Don’t worry. We’ll show you another way of doing it. But first, back up all your data.

  1. Type regedit into the Windows search bar and press Enter to open Registry Editor
  2. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsStore key

  4. Change its name to RemoveWindowsStore and assign it a value of 1. If you can’t find WindowsStore Key, you’ll have to create it.                                              If you can’t find WindowsStore Key, you’ll have to create it

Restart Your Computer

By disabling Windows store, you’re basically eliminating possible installation or update of third-party Windows Store apps.

When you try to open the Windows Store app after this fix, you will see this message on your screen:

Windows Store isn’t available on this PC. Contact your system administrator for more information.

NOTE: You need this feature to update apps like Calculator, Movies & TV, Mail, OneNote, and Photos. Therefore, if you need automatic frequent updates on these apps, we would not recommend disabling this feature.

Disable Superfetch and Windows Search Services

Another solution to this pesky problem is disabling Superfletch and Windows Search services. This solution works for most users, so it might be worth giving it a try.

Follow these steps:

  1. Press Windows key + R to open the Run dialogue box
  2. Type services.msc into the dialogue box and hit Enter
  3. Find Superfetch and click on it
  4. Click the run-down menu right besides Startup Type and select Disabled
  5. Click Apply and then OK
  6. Now go back and locate Windows Search from the list of services and double-click it
  7. Again, click the drop-down menu besides Startup Type and select Disabled
  8. If service status is Running, click on Stop
  9. Click Apply and then OK

That’s all! Now check if the error is resolved.

Run a System Scan

If you have tried all the solutions above but the problem still persists, you may have to run a system scan.

Use your preferred Antivirus program to perform a full system scan. Some antivirus programs have a malware scan feature.

After the scan, you will see if your computer has malware or a virus. If you find any, move to quarantine or delete them.

Restart your computer for the changes to take effect.

Check if the problem persists.

Perform a Clean Boot

If none of the solutions helps, you may have to perform a clean reboot. This way, the operating system will only run a few important startup programs and driver sets.

As such, you will be able to isolate the problem manually if the culprit is startup programs.
