Okay, that makes sense. Since software is usually licensed single-user I don't see any good utilities to move programs. Some people recommend that you move the disk drive from the old computer and then you need to do a repair on the windows installation to make it recognize the drive from the old computer.
I think most people just re-install the software they need. I recently did it twice and it doesn't take as long as you might fear, and you can download virtually anything with a fast internet connection these days.
