Hi Russel,

As per your query, I like to inform you that; Shellexperiencehost.exe contains information about single file with specific attributes, it is an executable file. You could face the high CPU usage due to any third party application which is trying to use this process.

The Run maintenance task checks issues that might slow down your computer's, such as how many users are currently logged on to the computer, whether multiple programs are running at the same time and which application is using more CPU usage.

Follow the below steps.

2. Select Control Panel.

3. Select Troubleshooting.

If the issue persists, perform Clean boot and check if it helps.

A Clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program.
