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?
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
I am now seeing moments when it goes up to 10%+ with the taskbar auto hide on. However, it does not seem to be staying high for very long or as long as it did with the other two updates. Still not perfect or completely fixed.
It would be nice to have some type of acknowledgment from Microsoft as to whether they are looking at the issue or not.
Because of using RDP so much for working from home, I need the Auto Hide turned on.
Ran an In-Place upgrade and I now see what ssgt_henry is seeing. Explorer.exe still spikes up on CPU usage but, doesn't stay there. Also doesn't hang/get stuck... just FYI
Now I am seeing the Auto Hide getting turned off some how. I will turn it on, see the explorer.exe ramp up to about 10% for about 20 to 30 seconds. Then back down. Sometime late I will notice that I cannot get to the task bar while using RDP. I will minimize the RDP and check the Auto Hide for the taskbar and it will be unchecked. What is going on???? This is a MS forum. Why are we not hearing anything from MS on this.
I had this issue with a client.
For them, the issue was fixed by uninstalling the March Windows Update however the issue also went away when they disconnected the USB DisplayLink docking station from their laptop.
So it was a combo of the March update and the DisplayLink dock. The only way to get the problem to go away with the DisplayLink dock connected was to uninstall the update. However, the CPU usage dropped from 25-30% with the update installed down to 15-20% after uninstalling the update, but even though explorer was at 15-20% the system was much more responsive with the update uninstalled.
I also updated the Intel and DisplayLink drivers, that didn't fix the issue but it didn't hurt it either.
I clean inistalled windows 11 a couple of days ago and noticed this issue, it only happens when "auto hide taskbar is enabled" am not sure about you guys but I have a laptop and its connected to a display and changing "When using multiple displays, show my taskbar apps on" to "Main taskbar and taskbar where window is open" fixed the issue for me, I also removed all taskbar overflow icons my this one too, I didnt test it on a single display so this may not work for you
