Not at all...............and a better question is WHY NOT? The cleaner you can keep your drive with OS on it the better. And, if you decide to format and reinstall you dont loose data or have to quickly burn it off to keep it............and too............why not partition and use Norton Ghost to image your OS.......then you want to redo your OS ..........you can reghost and be back up and running just like before in less than 5 minutes.
Good luck,
