I just did the same and was informed by a knowledgeable custom computer builder that you can take a program like Acronis True Image, NOT install the program, but still make an image file of your C drive using the program, that comes in handy in just these kind of situations. In fact, I already had an image file that I used, that was on a "samples" drive, that got me going much quicker. I've since updated/created a newer image file that contains all the additiional programs, plugs, etc that I also have installed, since that original image file.
My biggest headache was Toontrack, which I did NOT have on my original C drive image, and thus required all the recent updating, registering...and all that stuff again. This latest image will not require having to go thru that again.
Btw, I got my Acronis HARD COPY by ordering online, which is the *format* what you want, for about $25... about 1/2 at what you'd spend at a "Best Buy", etc.
