Hey, 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.

Solution
right click start
choose windows terminal (admin)
If it doesn't open in powershell, click the arrow next to the + on the taskbar of the app and pick Powershell
type SFC /scannow and press enter
once its completed, copy/paste this command into same window:

Repair-WindowsImage -Online -RestoreHealth
and press enter


SFC fixes system files, second command cleans image files, re run SFC if it failed to fix all files and restart PC

that was one way to fix it in win 10.

Another was to run a troublshooter but I can't see the one they suggest in win 11
They are under system/troubelshoot but advice is to run one under system & security and that header doesn't exist.

Try a clean boot and see if it changes anything - make sure...

Try a clean boot and see if it changes anything - make sure to read instructions and make sure NOT to disable any microsoft services or windows won't load right - https://support.microsoft.com/en-au/help/929135/how-to-perform-a-clean-boot-in-windows

All clean boot does is stops programs from running at startup, it doesn't remove anything

if clean boot fixes it, it shows its likely a startup program. You should, over a number of startups. restart the programs you stopped to isolate the one that is to blame.
