As a silver surfer, I have just built a good quality computer for my 38 year old daughters birthday. I have also purchased a new version of Windows XP Pro which I have installed on her system. My query is this: As she only uses a dial up internet system for her computer, it will take quite a long time to update all the programmes. (Anti-virus, Windows etc.) I personally use broadband. I have built this sytem at my home. If I arrange the settings for me, myself, to use my broadband, at my home, to update all the programmes on her new system, will this interfere with the activation of the Windows XP, when I install it in her home, and she uses her dial up modem to activate it. Remember I will have to change all the internet settings again so that she can use her own dial up settings. Thanks for all information given.
