This article is part of our course series
explaining various processes found in Task Manager, such as Runtime Broker
, and many others
. You don"t know what these services are? Better start reading! What is the host of the application framework?
This process relates to applications on the universal Windows platform, also known as Store applications - the new type of "applications included with Windows 10. They are generally acquired from the Windows Store, although most of the applications included with Windows 10 like Mail, Calculator, OneNote, Movies & TV, Photos and Groove Music are also UWP applications. More specifically, this process is responsible for displaying these applications in frames (windows) on your desktop, whether you use Windows 10 in desktop mode or in tablet mode
If you forcibly stop this process, all of your open UWP applications will close. RELATED: Why (most) Desktop applications are not not available in the Windows Store
These applications are more sandboxes than traditional Windows applications
. Unlike traditional Windows desktop applications, often called Win32 applications, UWP applications are limited in what they can do. For example, they cannot spy on data contained in other applications. This is probably why they need an additional process to display their content on the Windows desktop. However, Microsoft does not provide any official documentation explaining exactly what this process is responsible for. Why is it using CPU and memory?
" style = "max- height : 400px; max-width: 99%; "> In normal PC use, the application frame host process should remain in the background and use only a small amount of CPU and memory. When we launched eight UWP applications on our system, we saw its memory usage reach only 20.6 MB. The process used less than 1% of CPU for a few moments when we launched a UWP application, and otherwise used 0% CPU. We have seen some reports that this process can use a large amount of CPU in certain situations. We don"t know what can cause that, and it looks like a bug somewhere in Windows 10. If you find that this process is using too much CPU, we encourage you to just log out of Windows and youreconnect (or end the process in the Manager task, which will also close your open UWP applications). This will cause Windows to restart and hopefully the issue will be resolved. RELATED: How to Repair Corrupt Windows System Files with SFC and DISM Commands

. Can I turn it off? You cannot actually disable this process. If you right click on it in Task Manager and select "End Task, the process will be closed. All your appsOpen UWP or Store applications - the new type of application included with Windows 10 - will also be closed. However, the next time you open a UWP application, Windows will automatically launch the application framework host process. It started as required by Windows 10 in the background, and you can"t stop it. Is it a virus? To verify that the application framework host process is running on your system is the real thing, right click on it in Task Manager and select "Open location of the file".
