How to Enable or Disable Save Taskbar Thumbnails to Cache in Windows 10
In Windows 10, when you hover over a taskbar button of a running app or a group of apps, a thumbnail preview appears on the screen. For a single window it shows a single thumbnail, and for multiple windows it shows a number of thumbnail previews in a row. Windows 10 uses a cache for these thumbnails to show them faster. Sometimes it becomes broken, so you see an outdated or corrupted thumbnail preview.
In Windows 10, File Explorer is able to show small previews for image and video files you have stored on your disk drive. To speed up this process, it uses a cache file hidden in the user profile directory. When a file is cached, File Explorer reuses the thumbnail from the cache to show it instantly. Some users have noticed that Windows 10 deletes the thumbnail cache automatically.
