Windows uses a thumbnail database for media files like photos and videos and documents like PDFs, Word documents, PowerPoint presentations, etc. These small graphic files are used by Windows 11 to show a quick preview of the content within the files present inside a folder. These thumbnails are automatically generated and removed by Windows whenever you create, copy, or delete a file on your computer. So that the next time thumbnail is picked directly from the thumbnail database instead of creating a new thumbnail, this makes your computer run smoother.
However, if the Thumbnails Cache Database is too large as you frequently add and remove files on your computer or the database is corrupt for some reason, you may see the missing thumbnail issue in Windows 11.
In such a condition, you need to delete the thumbnail cache database so that Windows may create a new database. This will solve the missing thumbnail issue if it has happened due to a database error.
