That's not what I meant to say. The IContextMenu belongs to a shell folder 
object (given by the pSFParent member of ItemCmImpl). You should query this 
shell folder for what it supports via it's GetAttributesOf method (The flags' 
SFGAO prefix is an abbreviation for ShellFolder::GetAttributesOf). As far as 
I understand the MSDN documentation, with the CMF_CANRENAME flag in 
IContextMenu::QueryContextMenu the application tells the context menu if it 
wants the "Rename" option to be shown. So you should display the "Rename" 
option iff CMF_CANRENAME is set in uFlags and pSFParent->GetAttributesOf 
returns the SFGAO_CANRENAME flag.

All I've said so far are assumptions, based on MSDN an my own understanding of 
the topic. Both have proven to be incorrect often, so you probably should 
write some unit tests to figure out the correct behaviour on windows.

Bye,
