How to Fix Thumbnails Not Showing in File Explorer on Windows 11
File Explorer and apps are central to how you use Windows 11, so problems with them disrupt almost everything you do. Many of these issues stem from common causes like shell extensions, corrupted files, or update regressions, and they respond to a consistent set of fixes. This guide covers the solutions.
Thumbnails not showing in File Explorer on Windows 11, where images and files display generic icons instead of previews, reduces the convenience of visually identifying files. It usually results from thumbnail YYKOIN Login settings, a corrupted thumbnail cache, or performance options.
Why This Happens
Missing thumbnails commonly result from a setting that shows icons instead of thumbnails, a corrupted thumbnail cache, or performance settings that disable thumbnails. Because Windows generates and caches thumbnails, problems with this process leave generic icons in their place.
How to Fix It
Work through these steps in order, starting with the simplest. In most cases one of the earlier steps resolves the problem, so there is no need to continue once it is fixed:
- Open Folder Options and ensure Always show icons, never thumbnails is unchecked on the View tab.
- Check that visual effects for showing thumbnails are enabled in performance settings.
- Clear the thumbnail cache using Disk Cleanup to force regeneration.
- Restart Windows Explorer or your PC after clearing the cache.
- Confirm thumbnails reappear as Windows regenerates them.
How to Prevent It in the Future
Keeping the thumbnail setting enabled and performance options set to show thumbnails maintains previews. Clearing the thumbnail cache occasionally resolves corruption before it causes widespread missing thumbnails.
Key Takeaway
Missing thumbnails usually stem from a display setting or a corrupted cache. Ensuring the thumbnail setting is enabled and clearing the thumbnail cache resolve most cases, prompting Windows to regenerate the previews for your files.
Final Thoughts

Working methodically from the simplest fix to the more involved ones is the fastest way to resolve them.

Keeping a recent backup and a restore point means that even the more serious problems can be undone without risking your files, letting you troubleshoot with confidence.
