Hi Magnus,

seems notepad.exe and few other windows apps are doing it for
themselves...  So, I've added an option to disable the quoting and

New test build:

Try: VBoxManage guestcontrol <vm> exec [creds] --unquoted-args -- \
         c:\windows\system32\notepad.exe test=\"test\"

Notepad should now see test="test" and tell you off for giving in an
incorrect name.

Note! The --unquoted-args option only disables the final
RTGetOptArgvToString(,,MS_CRT) right before CreateProcessW is called
on the guest side.  On the VBoxManage command line, the shell/CRT will
interpret your command line first and turn it into argv, which is send
to the guest, thus the escaped double quotes (\").

Kind Regards,
