Wsappx Causing High CPU Usage. How To Fix It?

Wsappx Process Is Causing High CPU Usage. What Is Wsappx And How To Reduce CPU Usage Caused By It

Wsappx is a legitimate Microsoft Windows process that can be found on the Windows 8 and Windows 10 operating systems. This process can be seen running in Task Manager under Processes. The wsappx process is related to Windows Universal Apps (WUA) and Windows Store and runs in the background. Double-clicking the wsappx process will reveal two additional sub-processes running under wsappx: AppXSVC and ClipSVC. AppXSVC provides infrastructure support for deploying Store applications, whilst ClipSVC provides infrastructure support for Microsoft Store.

You may have noticed that the wsappx process consumes a significant percentage of CPU (Central Processing Unit) power when installing, uninstalling, or automatically updating Microsoft Store apps.

This is normal operation of the process and you should not need to take any action, however, it is possible that this service is having issues trying to install, uninstall, or update an app - this might cause higher than normal CPU usage over an extended period. In the guide below, we describe how to fix potential problems related to the wsappx process and high CPU usage.

Run Windows Store Apps Troubleshooter

Windows includes a number of troubleshooters designed to quickly diagnose and automatically resolve various computer problems. Troubleshooters cannot fix all problems, but they are a good place to start if you encounter a problem with your computer, operating system or connected devices. To start troubleshooting, go to Settings and type "troubleshoot", and then select "Troubleshoot" from the list.

Disable Windows Store Using Registry Editor

Windows Registry, usually referred to as just 'the registry', is a collection of databases of configuration settings in Microsoft Windows operating systems. It is used to store much of the information and settings for software programs, hardware devices, user preferences, operating system configurations, and more. Many of the options exposed in the registry are not accessible elsewhere in Windows. To edit the registry, you must use Windows Registry Editor. To open Registry Editor, open the Run dialog box (press Windows Windows key + R or right-click Start and select "Run") and type "regedit". Press Enter or click "OK".

Once Registry Editor is open, follow this path: "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsStore". You can copy and paste it into Registry Editor's upper bar if you wish. If the "WindowsStore" key does not exist, you will need to create it - right-click the "Microsoft" key, select "New", then "Key", and name it "WindowsStore".

Now select the newly created WindowsStore key and right-click its background on the right pane. You must now create a new DWORD value within the Windows Store key and name it "RemoveWindowsStore". Select "New", and then "DWORD (32-bit) Value".

Now double-click the created "RemoveWindowsStore" DWORD and set value data to 1. Click "OK" and exit Registry Editor. Restart the computer and Windows Store should now be disabled.

NOTE: Third-party apps cannot be installed or updated when Windows Store is disabled. If you need to re-enable Windows Store, undo the previous steps - simply delete the "RemoveWindowsStore" DWORD or set its value to 0.

Disable Windows Store Using Local Group Policy Editor

The Local Group Policy Editor (also known as gpedit.msc) is a Microsoft Management Console that allows users to manage Computer Configuration and User Configuration settings. By default, the policies that are set in the Local Group Policy Editor apply to all Windows user accounts. This feature is available only in Windows Pro, Enterprise and Education editions, and not others such as Windows Home Edition. If your operating system supports this feature, you can use it to disable Windows Store.

To open Local Group Policy Editor, launch Run, type "gpedit.msc", and press Enter to start it. Now follow this path: "Computer Configuration > Administartive Templates > Windows Components > Store". In the Store folder you will see several settings, one of which is named "Turn off the Store application". Double-click it, choose teh "Enabled" option and click "Apply" to save the changes and disable Windows Store. If you want to undo these changes, simply set "Turn off the Store application" setting to "Disabled".

NOTE: Third-party apps cannot be installed or updated when Windows Store is disabled.

Scan Your System For Viruses

It is possible that high CPU usage caused by the wsappx process persists due to malware or a virus. You can use Windows Defender (built-in antivirus program), which protects your computer against viruses, spyware, and other malicious software. Or, you can run another third-party antivirus if you have one installed. To run a full system scan using Windows Defender, type "virus" in Search and click the "Virus & threat protection" result.
