OK, thanks, so programs don't have to be in the registry to run? My dad was trying to explain this to me but I was kind of confused. He said most programs when installed, write in the registry, so it'd be possible on the initial computer I install them on, but on subsequent computers they probably wouldn't run? Also he said that I might experience some lag in the computer accessing the USB key...does anyone do this regularly, good or bad experience?
