XP去掉桌面小箭头

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Icons" /v 29 /d "C:\Windows\system32\shell32.dll,49" /t reg_sz /f
taskkill /f /im explorer.exe
attrib -s -r -h "%userprofile%\Local Settings\Application Data\iconcache.db"
del "%userprofile%\Local Settings\Application Data\iconcache.db" /f /q
start explorer

把上面文件复制到文本修改格式为reg运行。
