I have Windows XP MCE installed on my computer and am also using Norton Internet Security on it. Recently I was notified that the upgrade Vista disk is going to come in few days. I was therefore installed the Norton compatibility patch for Vista on my computer and it installed properly and Upgrade Advisor told me there is no problem with it. So I was wondering if I got my upgrade disk then will it be alright to leave Norton in place at the time of installation. What I mean to say is that will I be able to remove Norton first and reinstall it after Vista or keep it as it is since it will save some time for me. Any ideas?
