Why Is Windows Shell Experience Host Showing High CPU Usage? Certainly, it normally doesn’t use anywhere near the amount of processor resources being reported by annoyed users lately. It typically consumes little to no CPU resources. This is because it is not designed to be noticed. Normally, you won’t even notice the existence of the Windows Shell Experience Host. Over the years, it has been tweaked and refined with each new build of Windows 10, but its core functions remain the same. The process made its debut in the OS with the launch of Windows 10.

The Windows Shell Experience Host process handles universal app interface behavior with respect to elements like the taskbar, Start Menu transparency, calendar, clock, background behavior, etc. It is the component of the Windows shell (basically, the graphical user interface on Windows) that specifically handles universal apps. It is the Windows component responsible for the windowed display feature of universal Windows applications. The Windows Shell Experience Host is also known as ShellExperienceHost.exe.
