This is unfortunately (to me) ambiguous. Do you have the 100% identical 
(structurally) setup on both Linux and Windows, i.e. that the linked 
clone is there in both cases, set up in the same way?

It's expected behavior that this command does NOT delete all disk images 
used by this VM. It will only delete what isn't needed for other VMs, 
i.e. that part of the medium tree which is private to this VM. 
Everything else will be left over.

Your command is doing the same thing as "VBoxManage unregistervm vmname 
--delete", so if you think this is behaving differently on Linux and 
Windows then you need to describe exactly how you create the VM config 
(exact order of operations, probably it'd be helpful to provide the VM 
config files which you produce). Then we should be able to reproduce.
