Add rename to the menu:
HKEY_CLASSES_ROOT\CLSID\ {645FF040-5081-101B-9F08-00AA002F954E}\ ShellFolder
"Attributes"=hex:50,01,00,20
Add delete to the menu:
HKEY_CLASSES_ROOT\CLSID\ {645FF040-5081-101B-9F08-00AA002F954E}\ ShellFolder
"Attributes"=hex:60,01,00,20
Add rename and delete to the menu:
HKEY_CLASSES_ROOT\CLSID\ {645FF040-5081-101B-9F08-00AA002F954E} \ShellFolder
"Attributes"=hex:70,01,00,20
