1. 去除小箭头.

reg add "HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/Shell Icons" /v 29 /d "%systemroot%/system32/imageres.dll,197" /t reg_sz /f
taskkill /f /im explorer.exe
attrib -s -r -h "%userprofile%/AppData/Local/iconcache.db"
del "%userprofile%/AppData/Local/iconcache.db" /f /q
start explorer
pause

复制上面的代码。新建一个文本文档。粘贴后另存为*.bat文件，然后右击以管理员身份运行.桌面一闪,小箭头就不见咯.

2.恢复小箭头.

reg delete "HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/Shell Icons" /v 29 /f
taskkill /f /im explorer.exe
attrib -s -r -h "%userprofile%/AppData/Local/iconcache.db"
del "%userprofile%/AppData/Local/iconcache.db" /f /q
start explorer
pause

方法同上..此方法去除小箭头无任何副作用.网络上流传的有些方法不适合WIN10.会导致我的电脑右键"管理"不能用
