‘When a resource is scarce, you increase its yield’
Being quite a complicated and fragile system, your personal computer is home to some seemingly incomprehensible processes. No wonder, you are eager to know what they actually are and why your system needs them – especially if they consume too much of your CPU and memory.
Windows Shell Experience Host is a case in point. If you keep an eye on this process in your Task Manager, you see that it can go really heavy on your system resources.
As such, you might be willing to ask the following questions:
‘What is the Windows Shell Experience Host process?’
As part of your operating system, Windows Shell Experience Host serves as a kind of visual manager. Essentially, what it does is provide a windowed interface for universal apps on your computer. To be precise, the process in question is responsible for such graphical components as your start menu and taskbar transparency, background slideshow, calendar, clock, visuals, and other things.
Windows Shell Experience Host was first introduced in Windows 10 and has been properly patched since then. Therefore, these days this process is supposed to be rather thrifty with your resources. If it is not, chances are there is something wrong with your system.
‘Can I disable the Windows Shell Experience Host process?’
You can’t, and you shouldn’t. Disabling Windows Shell Experience Host will prevent you from getting the necessary visuals in Windows 10. Even if you try to end the process, your OS will start it automatically in a while. As such, if Windows Shell Experience Host eats up your RAM and CPU every now and then, your best bet is to troubleshoot the issue.
