Windows Thumbcache

Thumbnail Cache, a feature introduced in Windows operating systems starting with Windows Vista, enhances the user experience by caching thumbnail images of files. This functionality, when enabled, speeds up and makes loading these images more efficient in various views, such as File Explorer, by generating preview images or thumbnails for various multimedia files.

This artifact can provide evidence of the presence of files even if they have been deleted.
