What is Wsappx disk in windows 10

By Tapas Pal Updated

Ever wondered what Wsappx is? You might have not. But it is high time that you do.

This service, named Wsappx was introduced in the 8 and 10 versions of Windows. You might not feel the need to know a lot about Wsappx, as you hardly come across this.

But did you know that Wsappx, though running as a background service, captures a notable amount of your CPU and Disc storages? Yes, it does. Also, are you sure that it is not a malware?

Panicked already, isn’t it? Don’t be. Because you have reached the right place to clear all your doubts and sharp up your knowledge. The article I’m writing today is basically to enlighten you with every tiny detail related to Wsappx. So, read on.

What Is Wsappx?

Yes, let’s come to the point.

Wsappx is a pre-installed service that runs in the background, and that too occasionally. Wsappx file is from Microsoft itself, and it is very much secured in nature. Generally, it runs for a very short span of time and then shuts down automatically.


Wsappx is related to the Windows store app. It deals with services related to installing, uninstalling and updating of Windows store app. Also, it makes sure, that your Windows Store app is properly authorized and authenticated.

If you open the Task Manager on your PC, you’ll see Wsappx and three other apps running with it (Provided you’re using Windows 8 or 10). These apps are- the AppX Deployment Service(AppXSVC), Client License Service(ClipSVC) and Windows Store Service(WSService).

Now we will discuss elaborately, about these three services.                                                                                                                                                                                                                                  



AppXSVC or AppX Deployment Service does exactly what its name suggests. It provides structural backing to the Windows Store app. That is, it basically deals with installing and updating of Windows Store app. If this app is disabled for any reason, then the functions of Windows Store will also be affected temporarily or maybe permanently.

Sometimes while downloading some apps, you might see AppXSVC running in the background, even though you have not involved this app yourself. That’s because Windows store is updating this new app in the background.


As the name suggests, ClipXVC deals with client licensing and authorization. It makes sure that you’re only using those apps, which you have bought from the Store.

If you go to Services in your PC and search for the Client License Service app, you’ll see that Microsoft has described it as an essential app to run Windows store. It is also stated, if this app is disabled for any reason, you won’t be able to operate Windows store smoothly.


WSService, as illustrated by Microsoft, is another app which gives Windows store an infrastructural support. Without this app, Windows store would not work properly.

This app’s functions are more or less similar to ClipXVC.

Why Does Wsappx Use A High Amount Of CPU Storage?

Firstly, let me tell you the location of the Wsappx service. It is situated in: C:\Windows\System 32\svchost.exe\Wsappx.

Therefore, it is clear that Wsappx is located inside svchost, which is a system process that uses a high amount of memory. Svchost hosts several Windows services and shares many service processes. Therefore, it is evident that svchost.exe consumes a notable amount of RAM.

And Wsappx, operating inside svchost, is inevitably responsible for a major amount of CPU usage.  Whenever you’re downloading an app from Windows store, updating them or even removing them, Wsappx starts running in the background, causing memory usage.

On the other hand, if you disable the WSService or ClipXVC etc. in a rush, then you might end up with a badly performed Windows Store. So, think before you act.

How To Fix The Issue Related To Wsappx’s High CPU Usage?

If you are still having second thoughts regarding the excess usage of your CPU memory by Wsappx, here is what you can do to fix this problem.

By Increasing Memory

If Wsappx service is eating too much of your memory, then you can actually increase the size of your virtual memory to cope with that. Just follow the below-mentioned steps:

  • Go to Windows Search box and type Adjust Appearance and Performance Of Windows and hit Enter.                                                                                                                                                                                                                                                                 Adjust Appearance and Performance Of Windows
  • A tab named Performance Options will be opened. Click on the Advanced Segment.                                                                                                                                    Performance Options
  • In this tab, you’ll find a section named Virtual Memory. We are aiming to increase this one. So click on Change.
  • Now in the virtual memory tab, you have three things to do. First, uncheck the box next to Automatically Manage Paging File Size for All Drives.
  • Then select Custom Size. Under custom size, put the value of your current RAM in the blank space beside Initial size. And in the blank space below Initial size, e. the Maximum size put a value double the initial size. Both the values should be in MB.         virtual memory
  • Now just click Set and OK respectively and restart your system.

This will probably help.

By Disabling Superfetch

Superfetch is an active part of Windows’ memory manager, disabling it might give you a break from Wsappx. Follow the steps:

  • Type Services in your Windows search menu and hit Enter.
  • Find Superfetch from the list of Services and right click on it.
  • Now click on Properties to find a new tab.
  • Now change the Start-Up type to Disable and click Ok.                                                                                                                                                                                                         Superfetch
  • Finally, restart your PC.
By Disabling Windows Store

Personally, I don’t think you should disable Windows store. But if you are anxious enough with the high CPU usage of Wsappx, then you have the option to disable Windows store. Let’s see how.

  • First type gpedit.msc in the Windows search menu and press Enter.
  • Now keep clicking Computer Configuration-> Administrative Templates-> Windows Components-> Store.                                                                                                                                                                                                                                                       Store
  • Now in Store, find the Turn Off Store Application, and select Enable and Apply respectively.

You have now successfully disabled the Windows store.

Is Wsappx a virus?

Trust me; it is absolutely not a virus or malware or anything that could harm your documents. It is a part of Windows 8 and 10, and coming directly from the Microsoft house. It is completely safe and not at all a threat.

But if are still not convinced, then you can run an anti-virus scan, to verify what I said.


So, I believe I have discussed everything related to Wsappx. Now, you decide what you would like to do. Either keep it the way it is, as it is completely safe that way. Or disable it to stop the high usage of CPU it is causing you.

And don’t forget to covey me your opinion about the whole matter.
