Nowadays 32 or even 64 GB of RAM in a PC is becoming accessible for the average Joe.

Ideally I would like to be able to copy a fully working Windows 7 installation on DVDs or a Bluray disk and mount it in RAM each time I start the machine.

Is this possible ? If not, can I still install Windows on a ramdisk ?

The goal is to have something like a Windows live CD that would only operate in RAM and leave no trace since the machine would have no hard drive.

My google-fu returned tutorials for Linux, but I need Windows specific softwares. I could use a virtual machine, but I would prefer to keep things native.

All your suggestions are welcome.

This question came from our site for system and network administrators.

It might be possible to use Window 7's boot-from-VHD, keeping the VHD in RAM. – Breakthrough Aug 8 '12 at 13:49

You want to create a Windows Live Cd. A Live CD is effectively an installed version of the OS on a DVD/Blu-ray disk. There are several ways to accomplish this. My personal favorite is: Bart's PE. There are other ways too. Look for Windows Pre-installed Environment(WinPE). It is an official Microsoft Project for the same reason.
