virtualbox.org

I am using a Windows host to run several Windows and Linux virtual machines. I would like to be able to start the machines and just have them running without any visible windows. So far I have tried:

VBoxHeadless - starts the VM without the display, but still displays a console window
"VBoxManage -type vrdp" - appears to just call VBoxHeadless, still get a console
Using the COM API and calling openRemoteSession wiht type=vrdp - same as above.

Is there anyway on Windows to start a virtual machine without displaying any windows from the created machine?

Edit:
I have seen some hacks done with bat files to piece together a solution, but I would like to know if this is a supported scenario or something that will always have to be hacked to get to work.

I've posted a hack for this as well, I don't think this will be a supported feature in future versions.
