Each time I intsall recommended XP updates, I lose my Internet connection. Today, I installed them and Windows has frozen as it restarts. I CONTROL+ALT+DELETE does not shut Windows down so it's stuck in "closing down." Any suggestions about how to shut it down? Airport works great on the iMac every day, but connections thru Parallels are not reliable and often take days to get back. Any suggestions for better Internet connections? Thanks . Wayne
