Now that you are aware of the different causes of this problem. Let's explore some effective solutions that you can try:

Fix 1. Enable Windows File Explorer Preview Pane

If the preview pane is not working in your file explorer window for any file, then most probably it is not enabled. The simple solution to fix this issue is by enabling the preview pane.

Here is how you can do it.

Step 1: Open File Explorer by pressing "Win + E". Now click "View" > "Show" > "Preview Pane", and it will be enabled on your computer.

Note: The preview pane may be unavailable for narrow file explorer windows even when it is enabled.

Fix 2. Enable The Preview Handlers

Step 1: Open File Explorer and click the "Options" button (3-dots).

Step 2: Click the "View" tab and checkmark the "Show Preview Handlers" option. Now, uncheck the "Always show icons" option, then click "Apply" > "OK". Finally, you may restart the file explorer.

Fix 3. Enable Adjust for Best Appearance

Users who prioritize performance in their system settings may accidentally face this error with the preview pane. Tweaking performance options for the best appearance can resolve the problem, and here is how you can do it:

Step 1: Click "Windows" > "Settings" > "System" > "About" > "Advanced system settings" > "Advanced" > "Settings" to edit your performance priorities.

Step 2: Click "Adjust for best appearance" to select it and click "Apply" > "OK" to confirm.

Step 1: Open the Task Manager by right-clicking the Start icon and clicking "Task Manager" > "Processes". Now, right-click on the Windows Explorer process and click "Restart".

Fix 5. Restart Your Windows Computer

Steps: Click "Start Icon" > "Power" > "Restart" and wait as your PC restarts. You must save any unsaved work before following this step since you may lose progress without saving.
