Resetting or restoring thumbnails in Windows 10 is something that users tend to do on their computers, almost every now and then. This happens if the icons and/or thumbnails are in some way corrupted such that they are blank, or have been taken over by other apps, or they’re just not being displayed as they should in a normal situation.

In this case, restoring the thumbnails by resetting the icon cache can help resolve the issue. The same goes also for thumbnail cache, which is usually used to keep image previews, as well as previews of videos and documents.

Windows 10 usually keeps a cache database that houses thumbnail images for each folder, document, video and photo on your computer system, which is used to display a preview of the file quickly, or help you see the contents of a folder before opening it.

This problem grows over time as more folders and files are created, so the database can get corrupted, which manifests as the File Explorer displays incorrect thumbnails or the files don’t show previews of the same, or they could just not be there at all.

Thankfully, there are several solutions you can use to restore thumbnails in Windows 10 as listed below.

  3. Check folder settings
