What is “WSAPPX”? (All Queries and Problems solved)

You may have seen ‘wsappx’ process in Windows 8 and 10. Also, you might have observed that its consuming high amount of CPU and Disk resources. We will cover ‘wsappx’ in depth and resolve every problem related to it such as wsappx disk usage and CPU usage. Basically, its a process related to Windows Store and Microsoft’s new ‘Universal’ app platform.

You would like to read the following related articles:

  1. What is “COM Surrogate“?
  2. What is “Host Process for Windows Task“?
  3. Why we have “Windows Shell Experience Host“?

So, What exactly is “wsappx”?

wsappx is composed of two separate background processes which provide various System services and are very important. wsappx includes the AppX Deployment Service(AppXSVC) in both Windows 8 and 10. But on Windows 10 you will also see the Client License Service (ClipSVC). And on Windows 8 you will also see a process the Windows Store Service(WSService) in place of ClipSVC.

What exactly ‘wsappx’ does?

It handles:

  1. installing
  2. uninstalling
  3. updating

of Store apps and also ensures that they are properly licensed.

Based on your Operating System you will find 2 sub services associated with wsappx process. You can view it by expanding the wsappx process in Task Manager.

Lets now see, each of these sub services more clearly.

What is AppX Deployment Service(AppXSVC)?

It is responsible for deploying Store apps. All “Universal Windows Platform” apps are distributed under “.AppX packages”, therefore the name.

Also we can say that this service is responsible for installing, uninstalling, and updating Windows Store Apps. All the updates of apps related to Windows Store are done automatically by this service. There are many apps that fall under these categories which are as follows:

  1. Microsoft Outlook
  2. Paint 3D
  3. Camera App

Traditionally all Windows User Apps use CPU and disk whenever they are installed, uninstalled or are updated. But when we talk about Windows Store Apps, all resources consumed for installing the App or uninstalling or removing the App are shown by into AppXSVC Subservice under wsappx instead of that individual program.

Why “wsappx” is taking so much CPU and Disk Resources?

It’s because it is updating Windows Store Apps in the background or maybe you have chosen to install a particular app from Windows Store. So this explains why wsappx sometimes consumes so much CPU and Disk Resources in the background.

Let’s look at other sub services under wsappx.

What is Client License Service(ClipSVC) in Windows 10?

On Windows 10, ClipSVC provides many essential services that keep the Apps downloaded from Windows Store running properly. It acts as an infrastructure for all Window Store Apps.

If you disable ClipSVC then apps will not behave as expected and can crash at any time.

Several of the services provided by ClipSVC are:

  1. It performs license management of Store apps to check whether you have purchased the software or not. This is done for providing Anti-piracy in Apps.
  2. It will check whether the updates are available for the app and will notify the user?

There are many functions done by ClipSVC but Windows haven’t described it clearly so we can assume that its very important process for keeping our Windows Store Apps running properly.

What is “Windows Store Service (WSService)” in Windows 8?

Its functions are same as ClipSVC in Windows 10. It also provides services that are essential for the proper running of Windows Store Apps. ClipSVC and WSService have same descriptions by Windows in Service interface. This tells they are same services using different names in different versions of Windows OS.

You will not see the WSService process in Windows 10 and you will not see ClipSVC in Windows 8.

 Why “wsappx” is consuming so much CPU?

The wsappx services will consume a significant amount of CPU if you are installing, uninstalling, or updating Store apps. As you have chosen them to install or uninstall, so in the background it will install and thereby consuming CPU resources.

If you haven’t chosen to install or uninstall any app and then also CPU is consumed that means Store apps are being automatically being updated. So in the background, while updating the apps wsappx will consume CPU and Disk Resources.

However, you may not like sudden slowing down of PC because of automatic updating of Store Apps. Then you can turn of “Automatically Update Store Apps” option.

To disable Automatic Updates, do following steps:

  1. Launch Windows Store
  2. Click on User Icon on Top Right corner
  3. Go to Setting from the menu that appears
  4. Then, select Update Apps Automatically option and turn it OFF.


If you want to manually Update your Apps


  1. Goto Windows Store
  2. Click on User Profile icon at the top right corner
  3. Select “Downloads and Updates” option
  4. It will show you if any updates are available for installed Windows Apps.
  5. Select the App for which you want to update and install the updates.

By doing this wsapp will not consume CPU and Disk Space anytime but will do whenever you want it to do it.

But if you are using any of the Windows Store apps that come with Windows OS preinstalled such as Mail, Movies, TV, Photos, OneNote or Calculator, then turning off automatic updates is not recommended. As updates are very frequent for these apps therefore in order to get best features and proper running of these apps “Automatic Updates” should be turned on.

Can ‘WSAPPX’ be disabled?


Now you have understood its importance, then you would have realized that it’s not possible for you to disable it. wsappx will not be running all the time but whenever needed then only it will run in the background.

To notice this, just launch any Store App such as Music, then you will see ClipSVC process in Task Manager. If you launch Window Store then AppXSVC will start running. Whenever you install or uninstall any app then also AppXSVC will run in the background, therefore, consuming system resources such as CPU and Disk Space.

If you forcibly try to kill ‘wsappx’ process from Task Manager then it will warn you that its a system process and ending it will cause System to become unstable or will shut down. Therefore, there is no way to forcibly kill ‘wsappx’ process.

Hope you would have understood the importance of ‘wsappx’ and there is no reason to disable it. Although you can prevent it from automatically running in the background by turning off automatic updates.

Can ‘wsappx’ be Virus?

As you know that its a part of Windows 8 and 10 itself so there is no way it could be virus or worm. However, there is not virus till now which creates a process named ‘wsappx’ and does the dirty job. If you feel your computer is not running effectively even after the methods described above then it’s best to Scan your Computer for Viruses using a Good Antivirus Program.


WSAPPX is important service introduced in Windows 8.1 to help installing, uninstalling and updating Windows Store apps. They also help in running these apps. They will consume high CPU and Disk Space for some time only, therefore no need to worry if sometimes they consume it.
