This wikiHow article will teach you how to clear the thumbnail cache in Windows. A thumbnail is a preview of a file when viewed in File Explorer. On older versions of Windows, whenever you view a thumbnail in Windows, a file called Thumbs.db is created so that your thumbnails can load faster next time. On newer versions of windows, these thumbnails are stored in a central database. Old or new, this may take up large amounts of space on your hard drive or the thumbnails may eventually be broken, so sometimes it needs to be cleared.

Things You Should Know

Run Disk Cleanup in any version of Windows, then make sure "Thumbnails" is checked to remove the thumbnail cache.
You can manually delete the thumbnail cache by first showing Hidden Items in the File Explorer, and deleting any files that begin with the word "thumbcache".
Empty your Recycle Bin to fully delete the thumbnail cache from your system.

If you do this frequently, it can actually slow down your computer since Windows has to read the file and create the thumbnail instead of using the thumbnail cache. It is recommended that you only do this if you are experiencing issues with the thumbnails or it is taking up too much space.
