Fixing wsappx high memory and CPU usage

Question

I have seen this particular issue all over the internet. Mine started right after I converted my Windows 10 MBR drive to GPT. WSAPPX started randomly going as high as 12gb of memory usage and 100% CPU usage. Long story short, MY resolution was to disable the start-up "Send to OneNote Tool". The next reboot was perfect, and the issue has not returned. It has been 2 weeks. Hope this helps someone.

Hello ,

Good to see you in Microsoft Community.

Thanks for your sharing, that will help others with the same problem and provide us with new ideas and methods to solve similar problems.

Here are some information may help you about this:

"wsappx" is a process in the Windows operating system that's related to the Microsoft Store and Universal Windows Platform (UWP) apps. This process manages the installation, updates, and maintenance of UWP apps on your system.

The "wsappx" process is responsible for tasks such as:

1. Installing and Updating Apps: It handles the installation and updating of apps from the Microsoft Store. When you download or update an app, "wsappx" is involved in managing these processes.
2. License Management: It manages the licensing and permissions for UWP apps, ensuring that you have the necessary rights to use them.
3. AppX Deployment Service: "wsappx" is part of the AppX Deployment Service, which is responsible for installing and managing UWP app packages.
4. App Management: It can also handle tasks like starting and stopping UWP apps as needed.

It's worth noting that the "wsappx" process can sometimes consume system resources, especially during app updates or installations. If you're experiencing high CPU or disk usage due to "wsappx," it's generally because it's performing necessary tasks related to app management.

If you find that "wsappx" is causing performance issues on your system, here are a few steps you can consider:

1. Give It Time: Sometimes, "wsappx" might be using resources temporarily due to ongoing app updates or installations. It should settle down once these tasks are completed.
2. Check for Pending Updates: Make sure that all your installed apps are up to date. Sometimes, pending updates can cause "wsappx" to be more active. Or check for apps update in Microsoft Store: Open Microsoft Store*, click "Library" in the lower left corner, then you will see the installed applications, click "Get updates" to see if there are any available update, and click the "Update" button on the right to update.*
3. Limit Background App Activity: You can go to Settings > Privacy > Background apps and disable background activity for specific apps. This might reduce the impact of "wsappx" and other app-related processes.

If anything is unclear, please do not hesitate to let me know.
