Windows 7: How to use Windows PE to create a cd/usb boot enviroment that...

only start one program and nothing else..

I have been searching the net for a solution.

I have found this guide that explains pretty well what i want:
Boot to a Remote Desktop

But that was with BartPe and today i belive we use Windows PE.

The perfect solution would be to boot up Windows 7 from a USB/CD and ONLY have one program start. The guide above use RDP and that was my orginal quest but now i just want to be able for it to be any program.

No Windows 7 background
No Windows Start menu
No Windows Taskbar

Just a dumb color as background and then the program opens.

Ofcause there would need to be all the driver support that ships with Windows 7 cause i will be needing mouse, propper resolution, network and so on.

Any suggestion or Links as how i should start this projekt?

As it is now im tampering with Windows AIK to build a image, but i don't see how i get rid of the start menu and taskbar or make it start a program on boot. I can fix that with a script though..

Any ideas?
