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?

    My PC works ok when I do NOT hide taskbar automatically.

    When hidden automatically explorer goes to 10 - 20% and the taskbar is completely disabled. This takes couple of minutes and then everything works....untill it starts again. I may work some 15 to 30 minutes and after that I have exporer.exe peaking to 10-20% again and taskbar is disabled.

    I will continue using it without hiding the taskbar automatically and keep on waiting for a fix from MS. I also have all updates installed but the problem remains.

    I am having the same problem. And this update basically made my PC unusable for audio processing. But the funny thing is windows is not letting me uninstall KB5010414.

    Please report back after uninstalling KB5010414. I would be good to know that your PC is acting same way.

    Sorry, it did not mean that your reply was unhelpful, actually it was really good as I had previouusly determined same things to be done, but it did not resolve the problem.

    Just to let everybody know: it is working now. After uninstalling the latest updates the PC was working well. After testing for few hours I decided to try the updates again and now we have the latest updates and working PC. Explorer.exe is not using high CPU anymore.

    Thank you for assuring my own thoughts were on the right path.

    Case closed now.
