8 Ways to Fix ‘Shell Infrastructure Host’ High CPU Usage

If you are using a stable build of the Windows operating system, the Shell Infrastructure Host process is likely to run in the background and consume a small amount of Memory and CPU usage. However, sometimes, due to specific problems, the same process can raise CPU and RAM usage and freeze your computer.

If you are experiencing problems due to Shell Infrastructure Host high CPU usage, try these fixes.

1. Restart your computer

Restarting can sometimes resolve the most complicated problems on your computer, including system processes raising the CPU and RAM resource consumption.

Some apps may prevent the Shell Infrastructure Host from functioning, resulting in high CPU and RAM usage. So, before making any changes, restart your computer.

To restart your Windows PC, click the Windows Start button and Power menu and select Restart. This would restart your Windows computer.

2. Run the System Maintenance Troubleshooter

The System Maintenance Troubleshooter has a few links to the Shell Infrastructure Host. You can run it to resolve the high CPU and Memory usage caused by the same process.

1. Open the Control Panel from the Windows Search.

2. Click on Troubleshooting.

3. Click the View All button on the left pane.

4. Find and click on System Maintenance.

5. Check the Apply repairs automatically prompt and click the Next button.

3. Check for Program Conflicting with the Process

Boot your computer into safe mode and check whether the ‘Shell Infrastructure Host’ process still causes high CPU or memory usage. If there’s no such issue in a clean boot or Safe mode, you must find the problematic third-party software.

It’s pretty easy to find all installed software in Windows; you can access the Control Panel and remove all suspicious programs. Alternatively, you can look closely at the Task Manager to find programs running in the background without your consent.

If you find any apps that shouldn’t be on your computer, it’s recommended that you uninstall them.

4. Repair or Reset the Photos App

Corrupted Microsoft Photos installation files are said to trigger the problem. Hence, you can try repairing or resetting the Microsoft Photos app to resolve the issue.

1. Click on Windows Search and select Settings.

2. Switch to the Apps.

3. Select Installed Apps.

4. Click on the three dots beside it and select Advanced Options.

5. Scroll down and click on Repair. This will repair the Microsoft Photos app.

6. If repairing didn’t help, click the Reset button underneath the Repair button.

5. Run an Antimalware Scan

Windows Security is a great security program that ships with Windows 10/11. It can run a full anti-malware scan on your system. There are various ways to scan with Windows Security; here’s the easiest one.

1. Open the Windows Security app from the Windows Search.

2. Click on the Virus & Threat Protection.

3. Click on Scan options.

4. Select Full Scan and click Scan Now.

The full scan option will check all files and running programs on your hard disk. However, the scan could take up to one hour to complete.

6. Run the SFC/DISM Command

Another best way to resolve ‘Shell Infrastructure Host’ high CPU usage is by running the SFC and DISM commands. Both commands are designed to resolve problems associated with corrupted system files.

1. Click on Windows Search and type in CMD. Right-click the Command Prompt and select Run as administrator.

2. Type in sfc /scannow and press Enter.

3. If the SFC command returns an error, you need to execute this command:

DISM /Online /Cleanup-Image /RestoreHealth

The DISM command may take a few minutes to complete. You must wait until the command finishes fixing all your corrupted system files.

7. Perform a Clean Boot

A clean boot is performed to boot Windows with minimal drivers and startup programs. It disables most third-party apps installed on your device. So, if Shell Infrastructure’s high CPU usage issue doesn’t appear when you clean boot, you must find and remove the conflicting third-party program.

1. Press the Windows Key + R button on your keyboard. On the RUN dialog box, type msconfig.msc and press Enter.

2. Switch to the Services tab on the System Configuration and check the Hide all Microsoft services checkbox. Once done, click on Disable All.

3. Launch Task Manager and switch to the Startup tab. Right-click on the apps you don’t want to run at startup and select Disable.

After making the changes, restart your computer. This will clean boot your PC; check if Shell Infrastructure Host still raises the CPU bar.

8. Update your Windows Operating System

Updating Windows will likely rule out bugs or glitches that may conflict with the Shell Infrastructure host process.

Keeping your system updated is always a good idea to enjoy the new features and enhanced security & privacy options. To update Windows, open Settings > Windows Update > Check for Updates.
