If one or more of your icons are not displaying correctly, or that your icon cache is corrupted, then you might consider rebuilding the icon cache to reset and reload the icon images into the icon cache.
The icon cache is located at the hidden system folder location below:
C:\Users\User-Name\AppData\Local\IconCache.db
This will not help with any of the following icon issues:
-A shortcut's icon that is not displayed properly due to the source of the shortcut being moved or deleted. You may need to recreate a new shortcut directly from the source (ex: program's exe) file to replace it instead.
-All icons for a specific file extension display the wrong icon. This may be do to setting the wrong association for what program to open the file extension instead. You can restore the default file extension's associations to fix this icon instead.
