Explorer.exe high CPU usage after latest update, Win11

Anonymous

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?

    Hi

    Thank you for your fast reply.

    I already have done all things you proposed, did not help and no problems were found.

    Then I rushed a bit and uninstalled three latest updates from this week and voila...explorer.exe is not using high CPU anymore. Probably this was wrong way to fix because the updates are going to come in anyway.

    At the moment I just have to keep checking and see what happens. To my mind there was something in the updates which caused the problem.

    Anybody else with the same problem? Please inform!

    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.
