How to Clear and Reset Thumbnails Cache on Windows 11?

Windows has the thumbnail database it uses for media files and documents like photos, videos, PDFs, Word documents, PowerPoint presentations, etc. Windows 11 uses these graphic files to show a quick preview of the content in the files present in a folder. Windows automatically generates or removes these thumbnails as necessary whenever you create, copy or delete a file on your computer. As a result, your computer runs smoother since Windows won’t have to create a new thumbnail every time.

However, when you add thumbnails frequently, the Thumbnails Cache Database may get corrupted, and hence you may see the missing thumbnail issue on Windows 11.
