What causes the system's icon to display an exception

Q: I found that the icon color on the desktop has become 256 colors, and some display is abnormal. What is going on?
A: This is caused by an error in the icon cache. of. Windows uses icon caching technology to speed up the display of icons. Normally, the system will clear the icon cache from time to time. However, if the icon color and size settings in the current system are incorrect, the demand for the cache exceeds the default setting, or there is an error record in the cache, which may cause the icon to display abnormally. In this case, you need to manually delete the icon cache file so that the file can be recreated after the system restarts. The icon cache file is hidden by default, and you need to set the display hidden file to view it. In different versions of Windows, the icon cache file is located at:
1. For Windows XP: %userprofile%\\local settings\\application data\\IconCache.db
2. For Windows 98, Windows ME, and Windows 2000: Windows ( Winnt)\\ShellIconCache
