如果您的计算机运行缓慢^{(computer is sluggish)}，调查导致问题的原因之一是检查任务管理器^{(Task Manager)}。虽然任务管理器^{(Task Manager)}显示可能占用所有资源的正在运行的进程，但它不一定解释它们的含义。

Wsappx是您将在任务管理器^{(Task Manager)}中看到的那些不熟悉的服务之一。但是，即使您可以看到 wsappx 进程，也并不完全清楚它的作用。为什么它会占用大量的CPU和磁盘资源？

在本文中，您将了解 wsappx 导致CPU 使用^{(high CPU usage)}率高的原因以及如何修复它。

什么是 Wsappx？^{(What Is Wsappx?)}

Wsappx 是一个合法的Windows 服务^{(Windows service)}，众所周知它会导致高磁盘和CPU使用率。该服务处理Microsoft Store（以前称为Windows Store）和通用^(Universal)应用平台，始终运行。但是，它使用的资源量可能很少，也可能非常高，具体取决于您在做什么。

例如，如果您在 Microsoft Store 之外安装Microsoft Store应用^(Store)程序或桌面软件，则 wsappx 进程将使用更多CPU或磁盘资源。当您运行、更新或删除应用程序时，也会发生同样的情况。

为什么 Wsappx 会导致 CPU 使用率过高^{(Why Wsappx Causes High CPU Usage)}

在Windows 10上，wsappx 进程具有称为Client License Service或ClipSVC的子进程，以及AppX Deployment Service或AppXSVC。

ClipSVC服务处理商店^(Store)应用程序的许可并防止盗版^{(protects against piracy)}，而AppXSVC部署应用程序，以便它在您安装、更新或删除应用程序的任何时候运行。因此，如果您禁用其中任何一项服务，商店^(Store)应用程序将无法运行。

当子进程处于活动状态并正在运行时，您会看到 wsappx 进程使用率增加。虽然 wsappx 是一个重要的系统进程^{(vital system process)}，但它不必一直启用。仅当您要安装、更新或删除应用商店^(Store)应用时才需要它。

注意^(Note)：如果您使用Microsoft Store应用并收到有关许可的错误，则需要启用ClipSVC和AppXSVC服务。

当 Wsappx 导致 CPU 使用率过高时该怎么办^{(What to Do When Wsappx Causes High CPU Usage)}

当您看到 wsappx 使用大量CPU时，有几个修复程序可以解决该问题。

运行病毒扫描^{(Run a Virus Scan)}

Why Wsappx Causes High CPU Usage and How To Fix It

If your computer is sluggish, one of the ways to investigate what’s causing the problem is to check the Task Manager. While Task Manager displays the running processes that could be hogging all the resources, it doesn’t necessarily explain what they mean.

Wsappx is one of those unfamiliar services you’ll see in Task Manager. However, even though you can see the wsappx process, it isn’t entirely clear what it does. And why is it taking up a significant amount of your CPU and disk resources?

In this article you’ll learn why wsappx causes high CPU usage and how to fix it.

What Is Wsappx?

Wsappx is a legitimate Windows service that’s well known for causing both high disk and CPU usage. The service, which handles the Microsoft Store (formerly Windows Store) and the Universal app platform, runs all the time. However, the amount of resources it uses can be minimal or significantly high depending on what you’re doing.

For example, if you’re installing a Microsoft Store app or desktop software outside of the Store, the wsappx process will use more CPU or disk resources. The same happens when you’re running, updating, or deleting an app.

Why Wsappx Causes High CPU Usage

On Windows 10, the wsappx process has sub-processes known as Client License Service or ClipSVC, and the AppX Deployment Service or AppXSVC.

The ClipSVC service handles licensing and protects against piracy for Store apps while the AppXSVC deploys apps so it runs anytime you install, update, or delete an app. Thus, if you disable either of these services, Store apps won’t work.

When the sub-processes are active and running, you’ll see the wsappx process usage increase. While wsappx is a vital system process, it doesn’t have to be enabled all the time. It’s only needed when you want to install, update, or delete Store apps.

Note: If you’re using a Microsoft Store app and get an error concerning licensing, you need to enable the ClipSVC and AppXSVC services.

What to Do When Wsappx Causes High CPU Usage

When you see wsappx using up a significant amount of your CPU, there are several fixes to resolve the issue.

Run a Virus Scan

If your computer has a virus or malware, it can cause usage spikes in various Windows processes. The same is true if any downloaded or Microsoft Store apps are infected. Running a virus or malware scan will help you rule out the possibility that such threats are the reason for high CPU usage on your computer.

Update Windows

If the Microsoft Store won’t open or there’s a problem with the program, check whether there are any pending Windows Updates and install them.

1. To check for Windows Updates, select Start > Settings > Update & security.

1. Next, select Windows Updates and check the right pane for any pending updates.

Uninstall Recently Installed Apps

Sometimes high CPU usage may be as a result of an app you recently installed. In that case, uninstall the app and restart your computer. If this fixes the high CPU usage issue, try to reinstall the app and see whether the problem persists.

1. To uninstall an app, open the Control Panel and select Programs.

1. Next, select Uninstall a Program under the Programs and Features section.

1. Find the app you want to uninstall, right-click on it and select Uninstall.

Allocate More Virtual Memory

Increasing your computer’s virtual memory may help reduce the high CPU usage.

1. To do this, right-click Start > Search and type Performance in the search box. Select Adjust the appearance and performance of Windows.

1. Next, select Advanced tab, go to Virtual Memory and select Change.

1. Uncheck the Automatically manage paging file size for all drives box.

1. Choose your drive and then select Custom size.

1. If you know your device’s RAM, set it as the initial size (in MBs) and set the maximum size as double the RAM size. Select Set > OK and reboot your computer.

Disable Microsoft Store

You can disable Microsoft Store using the Group Policy Editor or the Registry Editor.

1. To disable Microsoft Store using Group Policy Editor, enter gpedit.msc in the search box and press Enter to open the Group Policy Editor.

1. Next, select Administrative Templates under Computer configuration.

1. Double click Window Components and select Store.

1. Double-click Store, and then look for the Turn off Store application setting on the right pane. 

1. Double-click Turn off Store application to open its settings windows, and then select Enabled > OK.

If your Windows version lacks the Group Policy Editor option, you can disable Microsoft Store using the Registry Editor.

1. To do this, right-click Start > Run.

1. Type regedit and press Enter to open the Registry Editor.

1. Go to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsStore

1. Create a new DWORD value in the Windows Store key and label it RemoveWindowsStore. Type 1 in the value field. Restart your computer and check whether wsappx CPU usage is minimal.

Note: Disabling Windows Store isn’t recommended if you need frequent automatic updates for apps like Photos, Calculator, Mail, Movies & TV, and OneNote. Plus, you can’t install or update third-party Windows Store apps when Windows Store is disabled.

Disable Automatic Store App Updates

Another way to reduce the wsappx high CPU usage is to disable automatic updates for Store apps to keep them from updating without your involvement.

1. To do this, type Store in the search box and select Microsoft Store to open it.
2. Click the Menu on the upper right side of the Store window and select Settings.

1. Toggle the Update apps automatically slider to turn it Off. This allows you to manually trigger app updates.

1. Click the Menu again, select Downloads and Updates, and select Get updates to check for updates. If you find any important updates, install them. 

Note: Remembering to check for updates manually isn’t easy for most people. Plus, apps are a major part of the Windows 10 operating system, so unless the automatic updates are grinding your system to a halt, we don’t recommend disabling them.

Remove Bloatware and Stop Background Apps

Bloatware and background apps tend to run when you don’t want them to, thereby increasing CPU usage on your computer. Removing bloatware ensures they don’t keep updating in the background and consuming resources.

1. To remove bloatware, select Start > Settings > Apps > Apps & Features to see all the apps installed on your computer. You can uninstall any app that you don’t use including pre-installed junk and other trash apps.

1. To prevent apps from running in the background, select Start > Settings > Privacy > Background Apps under App Permissions.

Disabling background apps from running means the app can’t check for new notifications when it’s not in use. You can disable background apps that you never use or toggle the slider to completely disable all background apps.

Other Fixes to Try

• Change AppXSVC Value in the Registry. You can do this in the Registry Editor. Navigate to the following key and change the Start value to 4.

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\AppXSvc

• Perform a clean boot to make Windows run startup programs and a few essential driver sets so you can check whether the high CPU usage is caused by startup programs.

Manage CPU Load

If you’re using Microsoft Store or apps are updating in the background, you may experience the wsappx high CPU usage issue on your computer, albeit temporarily. Try the solutions above and see whether wsappx goes back to normal levels.
