2. Click the respective search result.
3. Select the C drive and click the OK button.
4. Tick the Thumbnails checkbox and click the OK button.
5. Restart your computer and check your files in File Explorer.

It should fix the issue immediately.

2] Disable Always show icons

The File Explorer Options panel comes with an option that blocks Windows from showing thumbnails for all the files. If this setting is enabled, you can find the default icons instead of the file’s thumbnail. To verify or disable this option, follow these steps:

1. Search for file explorer options in the Taskbar search box.
2. Click on the individual search result.
3. Switch to the View tab.
4. Remove the tick from the Always show icons, never thumbnails checkbox.
5. Click the OK button.
6. Restart Windows Explorer using Task Manager.

After that, you can find all the picture thumbnails in File Explorer.

3] Enable thumbnails instead of icons

There is another setting in Windows that prevents the system from show thumbnails of your media files. To verify or turn on/off that setting, you need to follow these steps:

1. Search for advanced system settings and click on the search result.
2. Click the Settings button under the Performance tab.
3. Tick the Show thumbnails instead of icons checkbox.
4. Click the OK button.
5. Restart the Windows Explorer process.

Once you have done this, you will be able to see Thumbnail Previews for images, videos, and other file types in File Explorer in Windows 11/10/8.1.

You may be required to restart Explorer.
