如何删除桌面右键菜单多余项？

我要删除隐藏扩展名及文件、图形属性、图形选项这三条，怎么删除啊？

regsvr32 /u /s igfxpph.dll
reg delete HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers /f
reg add HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers\new /ve /d {D969A300-E7FF-11d0-A93B-00A0C90F2719}
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run /v HotKeysCmds /f
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run /v IgfxTray /f

新建个记事本，粘贴以上代码含绝，枯侍另保存为1.cmd后运没老吵行即可
