Alright, I've got a new build coming sometime this week. I've been operating on XP Pro for the last 7 years. I'll be installing Win7 Pro, and a new WDBlack 500gb HDD. I would like to copy over all my files and programs. Is it as simple as plugging the external into the computer, and moving them to the new blank disc? Can I do it without moving XP? Will there be any compatibility issues moving from a 32bit to a 64 bit OS? Will any I have to reinstall program,s or can they just move to the new HDD?
