well buddy uac is not a problem. can be disabled! he's a responsible comp user and knows what to install and what to shun!
yeah trying out is a good option. will download vista image and try out for a few dayz. he can't coz messing around his system will cause probs.
and
afaik the basic services are available wid the OS its fine.
hmmm... was browsing MS site and gotta know that there's no Anytime Upgrade for India. can anyone confirm this?
