What causes the System icon to display an exception

Q: Today I found that the icon on the desktop color turned 256 colors, and some show abnormal, how is it?

A: This is due to an error in the icon cache. Windows uses the icon caching technique to speed up the display of icons. Typically, the system empties the icon cache at times, but if the icon color, size setting in the current system is wrong, causing the need for caching to exceed the default setting, or if there is an error record in the cache, the icon may be displayed as an exception. You need to manually remove the icon cache file so that the file can be recreated after the system restarts. The icon cache file is hidden by default and needs to be set to show hidden files before viewing. In different versions of Windows, the icon cache files are located at:

1. For Windows xp:%userprofile%local settingsapplication dataiconcache.db

2. For Windows 98, Windows Me, and Windows 2000:windows (WINNT) ShellIconCache
