[Resolved] Unmasking the Hidden Culprit of High CPU Consumption: The Role Of Shell Infrastructures

Question : Recently I’ve noticed thatShell Infrastructure Host uses 50-70% of CPU power of my Windows laptop. Even after closing suspect apps, it’s still hogging a large part of CPU resources for hours. How to fix it?

Well, many Windows 10/11 users have reported this issue, so you are not alone. It mostly happens when performing common tasks like viewing photos on an internal or external hard drive or using a slideshow desktop background.

What’s Shell Infrastructure Host?

Shell Infrastructure Host , also known assihost.exe , handles the basic graphics UI elements like taskbar transparency, start menu layout, and even your fancy background image. Normally, it’s a quiet teammate, barely using any CPU resources. But like any good teammate, sometimes it stumbles. When that happens, sihost.exe can suddenly start hogging more CPU power than usual, leaving your computer feeling sluggish and unresponsive.

How to fix Shell Infrastructure Host high CPU usage?

Given below are the best solutions for Shell Infrastructure Host high CPU usage problem. You might not need to try them all. Just work your way down the list until you find the one that works for you.

It might seem obvious, but a simplerestart of your computer can often work wonders. It clears temporary files and resets processes, potentially giving sihost.exe a fresh start.

Fix 3: Use a different photo viewer app

One of the major causes of the Shell Infrastructure Host high CPU problem is the memory leak issue with the default photo viewer app in Windows. This bug makes sihost.exe query the registry all the time, which leads to the high CPU usage.

With that being said, using a different Photo viewer software is another easy fix for this issue. Just follow the steps below:

ClickStart , and selectSettings .
SelectApps.
SelectDefault apps , then clickPhotos (which is the default photo viewer app in Windows).
Switch to another app.

Then check if that resolves the issue. If nothing changes, you might need to repair corrupt system files.

Right-clickStart button and selectRun .
Typemsconfig and pressEnter .
On the Services tab of System Configuration, select Hide all Microsoft services , and then select Disable all . Click Apply .
On the Startup tab of System Configuration, click Open Task Manager .

Your computer may temporarily lose some functionality while in a clean boot environment, but that functionality will return when youreset the computer to start normally .

Find out the app or service that causes the issue

If the Shell Infrastructure Host CPU resource hogging issue doesn’t occur in a clean boot environment, you need to find out which startup application or service is causing the problem:

Enable the disabled services one at a time and restart the computer. If the issue reappears after enabling one of them, you need to uninstall this problematic software in order to resolve this issue.

But note that the most efficient way to do this is to test half of them at a time, thus eliminating half of the items as the potential cause with each reboot of the computer. You can then repeat this process until you’ve isolated the problem.

Reset the computer to start normally after clean boot troubleshooting

After you finish troubleshooting, follow these steps to reset the computer to start normally.

Right-clickStart button and selectRun .
Typemsconfig and pressEnter .
On the General tab, select Normal startup .
Select the Services tab, clear the check box beside Hide all Microsoft services , select Enable all , then select Apply .
Select the Startup tab, then select Open Task Manager .
In Task Manager, Enable all of the startup programs you had Disabled before, and then select OK .
When you’re prompted to restart the computer, select Restart .
