If your computer is slow, you can check Task Manager to see if any applications or services are hogging all the resources. If you come across wsappx as the culprit, you are not alone. It is well known for its high disk and CPU usage. While the name of the service doesn’t mean much to you, it is a legitimate Windows service and there are ways to reduce its high resource usage.
What is WSAPPX?
Wsappx is a service for both Windows 8 and Windows 10. It is part of the Universal Windows Platform and the Microsoft Store. Although it is generally running all the time, it generally uses minimal resources.
As you can see, wsappx at the time of writing was not using any CPU or disk resources. But that number can change quickly when you start using the Microsoft Store.
The process runs strongest while installing, updating, removing, and running apps from the Microsoft Store. It also runs when installing desktop software outside of the store. Don’t be too worried if usage increases, especially when you install, update, or remove an app.
While running an app, the process is also responsible for checking the license of the app. This is what increases usage when you first start using an app.
Do you need it?
Yes, you need wsappx. However, you don’t have to leave it on all the time. You should only enable it when using the Microsoft Store or installing, removing, or updating apps. Sometimes you may get a license error while using a Microsoft Store app. If so, you will need to activate the services behind the process.
The two services that trigger this process include AppX Deployment Service and Client License Service. On Windows 8, the latter is called Windows Store Service.
Expect temporary spikes
When you actually use the Microsoft Store, high disk and CPU usage is not uncommon. Even if you are not using the store at the moment, apps may update in the background, which temporarily results in increased usage.
However, wsappx should return to normal levels after the process is complete. In fact, even when I used the Microsoft Store, my CPU usage never increased by more than one percent, staying at around zero most of the time.
When your disk and CPU usage is excessive such as slowing down and approaching 100% of your system or not decreasing rapidly, you have a problem.
Below are several quick fixes that may work if you are just having the problem.
Start an antivirus scan
It may sound simple, but a virus can cause spikes in usage in a wide variety of Windows processes. If the Microsoft Store or downloaded apps are infected, you may experience high resource usage.
If there is a problem with the Microsoft Store, Windows Update may also install new updates for the Microsoft Store. This is especially true with major feature updates.
Uninstall the latest app
If the problem started right after installing a new application, delete the application and restart your computer. If this fixes the problem, try installing the app again, as it might not have installed correctly the first time.
Increase your virtual memory
It can help by allocating more memory to your computer. Open Start and type in “performance”. Select “Adjust the appearance and performance of Windows”.
Select the Advanced tab and press “Edit” under Virtual memory.
Clear the “Automatically manage paging file size for all drives” check box. Select your drive and select “Custom Size”. Set the initial size to your device’s RAM (in megabytes) and the maximum size to double.
Turn off the Microsoft Store
It’s a more drastic but effective solution if you don’t really use the Microsoft Store. If you have Windows 10 Professional or Enterprise, you have access to the Group Policy Editor. If you have Windows 10 Home, you can’t use this method, but there is a workaround.
First, to use Group Policy, tap To win + R and type
gpedit.msc. Press OK.
Then select “Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Store.” Select “Deactivate the Store app”.
Click on “Change policy setting”. Select On and press Apply.
If you can’t do this, you should use Registry Editor instead. If you do, be careful. Changing the wrong thing can damage your system. Please read these warnings, such as why you should back up your system and registry before continuing.
Open Start and type
regedit. Choose “Run as administrator”.
Select Yes when prompted.
Expand the following options:
If you don’t see WindowsStore, right click on “Microsoft” and choose “New -> Key”. Name it WindowsStore.
Right-click in an empty area in the right pane after you select Windows Store. Select “New -> DWORD (32-bit value)”. Name it “RemoveWindowsStore”.
Right click on it and choose Edit. Set the value to “1”. Restart your computer when you are finished.
Reset the value to “0” to re-enable the Microsoft Store, also known as Windows Store in Windows 8.
A mixture of all of the above can take to resolve this problem. Always back up your system before making major changes, for safety.
If wsappx is not the cause of high CPU usage in Windows, try some of these fixes.
