1.
运行注册表，依次展开到如下分支：KEY_CLASSES_ROOT\Directory\Background
\shellex\ContextMenuHandlers\New，然后在右侧窗口中新建一字符串值，并将其赋值为{D969A300-E7FF-11d0-A93B-00A0C90F2719}
2.
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder], 右边默认字符串值设置为"Folder"
3.
在设置完上边2条还是无效时，导入以下注册表项后按F5刷新
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\folder\ShellNew]
"Directory"=""
"IconPath"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,\
74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,73,\
00,68,00,65,00,6c,00,6c,00,33,00,32,00,2e,00,64,00,6c,00,6c,00,2c,00,33,00,\
00,00
"ItemName"="@shell32.dll,-30396"
"MenuText"="@shell32.dll,-30317"
"NonLFNFileSpec"="@shell32.dll,-30319"
[HKEY_CLASSES_ROOT\folder\ShellNew\Config]
"AllDrives"=""
"IsFolder"=""
"NoExtension"=""
4.如果是使用超级兔子后发现的右键新建缺少新建文件夹项，可以删除下边注册表项再按F5刷新。
删除HKEY_CLASSES_ROOT\FolderView.FolderViewCtrl.71项
删除HKEY_LOCAL_MACHINE\SOF
