I have a 2007 Gateway GM5688E. I got it at a steal because it was set up with an analog TV tuner and everything went digital. It's running Windows Vista and has a 320GB drive. I have less than 1% free space available.

I'd like to put in a terabite drive, install windows 7, and somehow move my programs over from the old operating system. I have a lot of weird specialty programs like Bantam Grass/Twig/Scatter, windome, Tree Generator. I have over 80 custom levels for Uru installed. I have Bryce with all the challenge mats and spent weeks loading Tony Lynch woods into material groups 1 page deep. Moving everything and re-entering CD keys will take literally months of work. Is there a program that will copy my operating system to the other drive?
