Summary

This guide helps you troubleshoot and resolve: How to Fix Windows 11 File Explorer Not Showing Thumbnails for Images and Documents. Follow the steps below to fix the issue.

Common Causes

File Explorer thumbnails allow you to preview images, PDFs, and other documents directly within Windows 11 without opening them. If your thumbnails are missing or displaying as generic icons, the issue is usually caused by a corrupted thumbnail cache or a changed view setting.

5. On the View tab, look for Always show icons, never thumbnails. If this box is checked, uncheck it.
6. Click Apply and then OK.

5. Ensure Display file icon on thumbnails is checked if you want icons to appear on top of image previews.
6. Click Reset Folders to restore default view settings for all folders, then click Apply and OK.

Troubleshooting

Thumbnails Still Missing for Specific File Types

If thumbnails work for some files but not others (for example, images show but PDFs do not), the associated application may not be installed or its preview handler may be disabled.

• Ensure you have a compatible application installed for the file type (such as Adobe Acrobat Reader for PDFs).
• Right-click a file of that type, select Open with, then Choose another app, and set the correct program as default.
• Restart File Explorer by opening Task Manager (Ctrl + Shift + Esc), finding Windows Explorer, right-clicking it, and selecting Restart.

System File Corruption

If thumbnails are missing across the entire system and none of the above steps work, system files may be corrupted.

1. Click Start, type cmd, right-click Command Prompt, and select Run as administrator.
2. Type the following command and press Enter: sfc /scannow
3. Wait for the scan to complete. If issues are found and fixed, restart your computer.

Group Policy or Registry Restrictions

If you are on a managed corporate network, thumbnails may be disabled by Group Policy.

1. Press Windows key + R, type gpedit.msc, and press Enter.
2. Navigate to User Configuration > Administrative Templates > Windows Components > File Explorer.
3. Locate the setting Turn off the display of thumbnails and only display icons.
