Wsappx High Disk Usage in Windows 10: How to Fix?

0

There are many things that make Windows computers or laptops run into performance issues and one of them is called wsappx. This is actually a process from the Windows 10 operating system and we’re going to talk about it in today’s article.

It seems that every now and then, wsappx has a high disk usage, usually combined with a high CPU usage and/or high Memory usage as well.

But what is this wsappx process and how to prevent it from slowing down your computer? This is what we’re going to talk about in today’s article!

What is wsappx and do we need it?

You probably figured it out by yourself already: wsappx is a process that is part of the Windows 10 OS. And if you’ve been using Windows for a while now, you probably found out that it starts reporting high disk usage and high CPU usage right after installing a new Windows 10 update or around the time when one is coming.

This is because wsappx is a process related to the Windows Store, mainly installing and updating the apps you have on your desktop computer or laptop.

This means that this is an important part of Windows and fortunately it will rarely cause problems. It will generally start to act up only when updates are required to your apps, during an important Windows update.

Therefore, although you can disable it (and we’ll tell you how), it’s best to just leave wsappx be and do what it has to – which is updating your apps. Afterwards, it will stop being an annoyance.

But if you want more control over everything, we’ve got you covered!

How to fix / disable wsappx to reduce the high disk usage or high CPU usage

There are a few ways for you to fix wsappx’ high disk usage and high CPU / RAM usage if they come together. I repeat, though: usually, simply waiting a few to several minutes (depending on your internet speed) will fix the problem, as the process will download the updates it needed and then stop causing problems.

But if you don’t want to wait, or if you simply want to turn it off or get more control over it, here is what you should do:

1. Diable wsappx by disabling the Microsoft Store

Although in many occasions useful, most people will rarely use the Microsoft Store after installing their main apps.

Even more, updates for these apps will be rare, so disabling the Microsoft Store completely might not be a horrible idea in most cases, especially if it causes performance issues.

Here is how to do it:

– Press the Windows Key and run, and type gpedit.msc in the new window:

IMPORTANT: Some Windows 10 versions don’t have this Group Policy Editor that you can access through gpedit – if you don’t have it, try the methods below.

– You will be taken to the Group Policy Editor – in the snap-in tree there, click Computer Configuration, then select Administrative Templates , select Windows Components, and finally select Store.

– Click the setting pane, then right click Turn off Store application, and select Edit from the new window.

– Finally, in the new window (Turn Off Store application), select Disabled, then Apply and OK.

This will completely disable the Microsoft Store and it will go in full effect after restarting your computer. Have in mind, tough, that doing this will prevent you from using the Store and your Apps won’t be updated anymore!

2. Disable the Store by editing the registry

IMPORTANT: Be very cautious when editing Windows registry files! Only do this if you are sure you have no other option and follow our instructions step by step to make sure you don’t break something. Even so, there are chances that something might still break.

– Press the Windows Key + R and type regedit in the new window:

– Navigate all the way to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsStore key

– You might not have the WindowsStore key created – in which case, you should create it now by right clicking Microsoft – New – Key and name it to WindowsStore

– Now, right click the right part and create a new DWORD (32 bit) Value:

– Name it RemoveWindowsStore and give it the value of ‘1’.

Restart your computer and the Microsoft Store should no longer run. If you want to reverse this, simply delete the WindowsStore key you have created or just the DWORD value.

3. Increase Virtual Memory

If the methods above don’t do the trick or are too complicated, you can try to increase your machine’s virtual memory to fix the high disk usage problems caused by wsappx. Here’s how to do it:

– In the search bar type “appearance and performance” and select the recommended entry:

– In the new window, click the Advanced tab, then the Change button under Virtual Memory

– In the new window, uncheck the “Automatically manage paging file size for all drives” option, select drive C (or the one where you have Windows 10 installed, if different) and click Custom Size.

– For the “Initial Size” value, type your current computer’s RAM (in MB), and the Maximum Size value to double that amount. Click on Set, then OK and restart your computer.

These fixes should help you with the high disk usage or CPU usage caused by wsappx. If you have additional methods to fix the problems, don’t hesitate to share them with us by commenting below.
