Gentlemen---thank you for responding but----I did it with no problems. I have a new HP9300 quad that came with 7 home premium. I bought the anytime upgrade and from what I read in this forum, this is merely a key to unlock what was already there not a download at all..Had I been familiar with the nuances of the various programs I would have started with 7 pro initially. I think for backing up I'll get an external hard drive or learn how to back up files only on DVD. I made the recovery disc's early on which is new to me. Used to get actual disc's to be able to re-install the program in olden days. Now, you make your own. Talk about pinching pennies. I won't go through the mantra of damning MS---got to appreciate what we have at our disposal today---I remember the punch cards initially. Also remember when a 40 megabite hard drive was a big deal.
