Windows 10: Windows 10 file explorer keeps locking up with fairly high CPU usage

Windows 10 file explorer keeps locking up with fairly high CPU usage,
I've tried disabling all the extensions in a binary fashion and it doesn't appear to be an extension causing the problem.
I've sun sfc and dust until no more errors get reported
I've updated to the latest build of windows

I've tried attaching a debugger to see if I can isolate where file explorer is hanging, but it doesn't appear that I am able to debug file explorer.
and finally, I've run out of ideas as to what it could be and google hasn't given me any other insight.

Windows Explorer high CPU Usage in Windows 10

Hi Andrew,

Usually, too many background processes can boost your CPU usage. Since you already disabled the apps that are not necessary on startup,
we suggest checking the applications running once you have successfully boot Windows 10. To do this, simply follow the steps below:

• Click on the Start button and type Task Manager on the search box.
• On the Task Manager window, you should see the programs running.
• Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

From there, you should see what applications are running on high CPU usage. You can also
restart the Windows Management Instrumentation service and see if your CPU performance will improve. Follow the instructions below to restart the service:

• Click on the Start button and type Services.
• Scroll down the list and look for Windows Management Instrumentation.
• Right click on it and select Restart.

Should you have further questions, please let us know.

 

Windows Explorer high CPU usage as Apps or Background Process...

3May2018...

Running Windows10 Home Ver 1709 latest OS Build on

Intel Core i5 CPU @ 3.8GHz.

Recently Windows Explorer has been running at high CPU usage 45% to 50%

Even when I am not using File Explorer - Windows Explorer runs as a Background Process as same high CPU usage...

First when will Microsoft stick to the new name File Explorer - instead of showing Windows Explorer as the app in the Task Manager...confusing :-(

Two - I saw someone else with the same problem and a ridiculous multi step cumbersome solution of creating another account (where Windows Explorer did not have high CPU) and then a painful exercise of trying to migrate all applications and files from one
account to the other.

Apparently the original user account may have had a corruption....

Are there any simpler explanations out there on how to fix run away Windows(File) Explorer???

 

Windows Explorer high CPU Usage in Windows 10

To further troubleshoot the issue, we suggest checking the Task Manager again to see what are the
applications that have high CPU usage. To do this, follow the same steps you did from the previous reply:

• Click on the Start button and type Task Manager on the search box.
• On the Task Manager window, you should see the programs running.
• Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

However, based on your response above, it seems that you may need to create a new user account again and just install your apps manually instead of copying them as your
previous user account might be corrupted.

Once your done with the steps, please let us know how it goes.
