I don't believe that's possible (but I may be wrong).
I believe the encryption key is generated when Win7 is installed. There is obviously some way of knowing that the key is part of THIS install of Win7, not a previous install. I'm sure Microsoft was quite successful in making this bulletproof.
So you can't just restore some file from the previous system and have it work with the current system as if it had been generated during the current system's install. There's obviously double-check and triple-check logic here, and crack-proof guarantees that you CANNOT do this... neither copying this "magic key file" to another machine, or even to this machine's new Win7 install.
The key is only good for a currently installed Win7. Period.
You'd better watch all of your copy-once content before you reinstall. That's the only solution that "works".
