Explorer.exe high CPU usage after latest update, Win11

I am running Windows 11 Pro 64 bit version 21H2, build 22000.527.

After the latest update explorer.exe started to grab occasionally about 20% to 50% CPU power. Upon this high CPU time taskbar does not work, applications already on the desktop work though.

I have checked the desktop folder for any files missing the icon and I have also disabled OneDrive, did not help.

This problem is on almost all the time. It easies down occasionally but starts again. If I have the computer locked and log in again the problem starts immediately.

I do have some applications in desktop right button menu but they were there before the update without any problem(7-zip, WinZIP, NitroPDF etc).

This is quite annoying and prevents me working with the PC. The computer is Lenovo Thinkbook with 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz 2.80 GHz and 16 GB RAM.

Should I try to uninstall the latest update and is there a change that it messes up the operating system?

    Luckily I have all my files in OneDrive replicated folder. Same thing with desktop.

    In my case it was rather easy. You need to copy your files in other location first.

    In my case I had to recreate my domain account also. You have to do that also if you are connected to domain.

    Try first to create a new account in Win 11 and check if that works ok…then you can determine that it is or is not a profile problem.

    I am experiencing the same issue on my PC. I will go through the doc's that Jerico posted to see if they work. If not I may do the SP uninstall and then reinstall. My PC is running on a AMD Ryzen 5 3600 6-Core and has 16GB memory.
