The command (now is "convertfromraw stdin" in 2.1.0) looks not applying to windows hosts, is it?

What gives you that idea? This is taken from a Windows machine:

VBoxManage convertfromraw   [-static] [-format VDI|VMDK|VHD]
                            <filename> <outputfile>
VBoxManage convertfromraw   [-static] [-format VDI|VMDK|VHD]
                            stdin <outputfile> <bytes>

That is what I get when issueing a VBoxManage.exe --help.

but

Usage:

VBoxManage convertdd        <filename> <outputfile>
VBoxManage convertdd        stdin <outputfile> <bytes>


Syntax error: Incorrect number of parameters

You misread the syntax. As you can see, there are two, almost identical syntaxis. The first is where you specify a source and destination, the other is the stdin line. Stdin means that it will ask you on the command prompt for the rest of the syntax. This is commenly used in Linux enviroments, but as Windows is more graphical, it's not so widely known to it's users.

Does stdin parameter apply to Windows?

Stdin is a globally used word for default input on a command line. So it applies to all Operating Systems.
