Windows 10: Unreasonably slow File Open/Save Dialogs and high resource usage on any application when...

Hello!This issue is on a Win11 Pro 22H2 Build 22581.200 machine but persists on other machines in our network.First of all: Windows Explorer is able to populate network directories instantly. This is not a configuration issue with the network settings on the machine.But: In any other application Chrome, Adobe InDesign, Photoshop, Acrobat, VSCode, Notepad...etc when using the Open/Save dialog, the directories load painfully slow. The speed of loading is mostly determined by the size of the files in the directory, NOT the number of items in the directory. I figured this out when I decided to o

Brevity can be a virtue but it can also be counter-productive.

File Open/Save Dialog causing applications to crash

Seemingly ever since the Windows 10 Creators Update installed itself on my computer, I've been having issues when using the File Open/Save dialog. If I try and open a file, save a file, or upload a file to attach to an email, the application that I'm using will crash (whether it's Chrome, Word, Paint etc). Edge, however, works fine and weirdly, Firefox also works fine.

I have been doing some debugging, trying to figure out what it could be, but I'm running out of things to try.

I've tried the following:

• Resetting folder views to default
  
• Enabling "Show all Folders" in Folder View Settings
  
• Starting computer in safe mode (where the dialog would work just fine)
  

I have also run some tests using MS Paint. I downloaded an application called DebugDiag 2, and had that watch the mspaint process to capture the exceptions thrown when the application would crash. These are the ID's of those exceptions:

• 0XC000001D
  
• 0XC000041D
  

Still using MS Paint as my test application, if I ran it as an adminstrator, I was able to use the File Open/Save dialog perfectly fine, but closing the application then reopening as a normal user would then end with the application crashing upon trying to open a file.

Another thing I've noticed is that when I first sign into Windows, I have about 30 seconds where I can open MS Paint, and be able to use the File Open/Save dialog just fine. After that time, if I close the dialog and then try to use it again, the application will crash.

I've read online that this issue is sometimes caused by the File Open/Save dialog trying to show a folder that no longer exists, or is on an unreachable network drive. So with that in mind, I have restarted my computer (getting that 30 seconds of grace when I first sign in) to be able to open MS Paint, and save a new file to my downloads folder, in the hopes that it would update the "last used folder". Unfortunately, this didn't solve the issue.

Is there anything else I can try?

 

High CPU usage

Hi Tusar,

The Task manager shows high CPU usage for core Windows process which can be used by other application. In order find out which applications might be using more resources through these services, I would suggest you to open 'Resource monitor' and check. In
task manager, go to the 'Performance' tab and click on the option 'Open Resource monitor' option at the bottom. Click on the CPU tab and then select the processes which showed high CPU usage in task manager. No expand the 'Services', associated handles section
and post us a screenshot so that we can check the details and help you accordingly.

In the meantime, I would also suggest you to boot the PC in safe mode and check if the issue persists. Refer to this article:
