I have Windows XP Home installed on my computer. I want IIS(Information Interchange Server) to be installed. I have learned from a friend that IIS is only available with Windows XP Professional. If this is so then can I upgrade from Windows XP Home to Professional to install IIS or do I have to reinstall Windows XP Prof.? I do not want to reinstall because I will lose my settings for various softwares as I would have to reinstall them too. Please advice as to what I should do?
