I'm beginning to get very frustrated with Windows Explorer.

Specs: Edition Windows 11 Home Version 21H2 Installed on ?2021-?07-?29 OS build 22000.348 Experience Windows Feature Experience Pack 1000.22000.348.0

(I'm on the Beta channel)

Windows Explorer is very slow (5-10 second opening time, blue loading cursor) when:

  • Navigating files normally in the "main" pane (double-clicking folders, opening files)
  • Right-clicking on anything, anywhere

However, it's regular speed when:

  • I'm using the standard file picker (i.e. Open/Save)
  • I utilize the breadcrumb bar to drill down into file trees (vs double clicking folders in the main pane): Screenshot of breadcrumb nav
  • I click on any folder/drive in the quick access sidebar

I've had these issues since upgrading to Windows 11 in the summer.

Any ideas what may be causing this? Any temporary fixes?

Would be glad of your help.

  • Well, I can only guess: If you changed files recently, or did not use the computer for a while, Windows defender might scan all the files in the folder. If you sync with a cloud, it may be slowing down things. Some add-ons may be triggered to examine the files, too. But in general it's amazing how terribly slow Windows can be when searching files.

There are two things you can try:

1. First, DISM / SFC:

(1) Open cmd.exe with Run as Administrator.

(2) DISM.exe /Online /Cleanup-image /StartComponentCleanup

(3) DISM.exe /Online /Cleanup-Image /Restorehealth

(4) SFC /SCANNOW

(5) Restart when all the above is complete and test.

2. Windows 11 Repair Install:

If this does not work (and DISM / SFC are basic and have limitations) you may need to try a Windows 11 Repair Install.

Windows 11 is running, so click on the Download button (not Upgrade Button) and select Run. Use the Download button to create a USB Windows Installation key, then run Setup on the USB Key.

Running Setup will launch the Repair Process.

I have done this on Windows Insider (Beta) and it works fine.
