Windows10系统，每次长时间无动作屏幕关闭后再重新亮屏，右下角任务栏的图标就会糊成一坨，有时候甚至变成一个个黑色块。
运行如下bat脚本重建缓存可以恢复正常，但我实在好奇这是什么原因，有人遇到过相同情况吗？
rem 关闭Windows外壳程序explorer
taskkill /f /im explorer.exe
rem 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\*"
