Issue: How to fix Shell Infrastructure Host high CPU in Windows?

Hello, I have a problem with my Windows laptop. I have recently noticed that Shell Infrastructure Host high CPU – usually 50-80% when my PC is idle. Can I end this task without doing any harm? Please advise what to do otherwise.

Solved Answer

Task Manager is a great built-in Windows element that can help users observe which processes are currently running and how many resources are used by them. While third-party applications often bring in their own processes, there are plenty of built-in processes that are used by Windows. In fact, some of them are vital for the normal operation of the system.

Some users have recently experienced an abnormal CPU usage of Shell Infrastructure Host. Under normal circumstances, it shouldn't costume more than three percent of the CPU. Unfortunately, some users reported that they've seen the process spike as high as 60%, which is surely not normal behavior.

To clarify the situation, we must first look at the process and what it does. Shell Infrastructure Host usually runs under the sihost.exe file and is a core component of any Windows operating system. Its main function is to support the start menu layout, taskbar transparency, and other graphical UI[1] elements of Windows.
