If you're referring to the picture preview shown on the folder icon itself, Windows 11 uses a different folder design than Windows 10. While there isn't a built-in setting to restore the exact Windows 10 folder appearance, you can try refreshing the folder thumbnails to see if larger previews return. The original thread indicates that more information is needed to determine whether the concern is the folder icon preview or the image thumbnails inside the folder.
As a quick check, please try:
- Open the folder that contains your pictures.
- Click View and select Large icons or Extra large icons.
- Verify whether your photos display as thumbnails inside the folder.
If the issue is specifically the folder icon appearance, please let us know whether:
- The picture files open normally and show thumbnails inside the folder, or
- Only the folder icon itself looks different from Windows 10.
A screenshot would also help clarify exactly which view you're referring to so the most appropriate guidance can be provided.
