系统图标缓存出了问题，只要把系统图标缓存清理1下，然后让它重新再生成缓存图标，图标就恢复了。以WIN7系统为例，清理缓存方法如下：rem 关闭Windows外壳程序explorertaskkill /f /im explorer.exerem 清理系统图标缓存数据库attrib -h -s -r "%userprofile%\AppData\Local\IconCache.db"del /f "%userprofile%\AppData\Local\IconCache.db"attrib /s /d -h -s -r "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\*"del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_32.db"del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_96.db"del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_102.db"del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_256.db"del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_1024.db"del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_idx.db"del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_sr.db"rem 清理 系统托盘记忆的图标echo y|reg delete "HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify" /v IconStreamsecho y|reg delete "HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify" /v PastIconsStreamrem 重启Windows外壳程序explorerstart explorer将以上代码粘贴到记事本，然后保存为“重建缓存.bat”，用治理员权限运行就可以。
