I’m not sure what you mean by this? Windows XP has been the "standard" Windows platform for about five years now, and I am sure it will be used in many homes for several years yet. But it’s about time they had an upgrade!
Windows Vista looks decent from what I’ve read about it. Not sure about IE7 – looks like they are trying to ‘steal’ features from FireFox, i.e. tabbed browsing. I use FireFox 99% of the time anyway, so I don’t know if I will bother downloading IE7 right away.
