ok, for the most part this is correct, however, if you are going to do this please remember that many programs require keys to be added to the registry or dll files to be modified.
if this is the route you choose, i would, find a program that back up changes to the registry, so that you dont get the entire regitry, and do that way, so that you dont need to reinstall
for instance, i redid my drives with a special utility that will remain anonymous, and resized and moved all my files, and my photoshop, cs2 couldnt find a file, which the registry pointed to, so that you couldnt crack it without that registry entry
another alternative, if you have a lot of ram, and this is just your computer, would be to download virtual pc from microsoft, for free, and install the os there, then every once in a while copy the "hard drive" as a backup, since its just a virtual hard drive its easy to copy, and you can make the size of it dynamic, meaning if its 100 GB it only uses what is needs, and expands as it needs to, maximizing at 100 GB
so good luck, and btw, microsoft generally rules these as seperate licenses, for the computer(s) but, i like to bend the rules from time to time....
