Hey, this is my first post and I hope I get a support.

A clean Windows 11 installation on Lenovo ThinkPad-P72, installed all the updates provided by Windows Update, when splitting the file explorer in two windows and starts copying pictures from a window to the other one, the Shell Infrastructure Host (sihost.exe) kicks in and stays on 16% CPU with high fan speed and If I continue working on the same task the PC gets stuck and I have to restart it to resume. I don't have this issue on my ThinkPad-P71.

Create another user account to find out if the high CPU usage by sihost.exe.

Ensure your PC is up to date.

It’s safe to run sihost.exe if it’s in the C: Windows\System32 folder.
If you locate sihost.exe in a different location (such as a subdirectory of Program Files), delete it right away.

Malware on your computer can cause a slew of issues, so take the methods below to scan your machine for viruses.

I'm also experiencing this from time to time. I regularly run SFC and DISM checks. What could the issue be?

I think there is bug with the Photos app in Win 11. I notice the high CPU on sihost.exe starts when using the photos app as well.
