If you encounter some program/file/folder icons that are not working properly when using the Win10 system, this may be due to an error in the system icon cache. This problem has also appeared frequently in previous generations of Windows systems, including Win7, Win8, and Win8.1. If you encounter this problem, please refer to the following method to solve.

In order to speed up the display of icons, the system will cache the files/program icons. These cache contents are stored in a cache file named Iconcache.db. When the user views these files/programs again. When you do not need to re-acquire the icon from a file such as a DLL, it will speed up the display.
