You can do it manually. The game folder can be freely copied to anywhere else, desktop shortcuts are easy to create so your only worry would be the aavefile folder...
if your new machine haa the same OS and user setup, the location will be the same.
If not, install the demo, see wheee it puts saves and then copy the old onea there.
and the samw for mods.
As far as I know, there is no magic in registry etc.
