I have been wondering about Microsoft eternal security updates for XP. Could they not have finished developing XP before launching Vista. My question is: do I really have to download all the updates if I am using a broadband router with a built in firewall as well as an up to date antivirus software? The updates are costing me a fortune in bandwidth as I have to update 4 PC’s on the network and each one downloads it’s own updates. Is there a way to download the updates and save it to deploy to the other PC’s on the network later?
