Hi. I just installed Windows XP SP1 onto my new hard drive because my other one is finished. I ordered the XP SP2 cd from the microsoft website and it should be here tomorrow or so. Should I wait before I install the updates that are ready for my computer right now from auto update or should I install these now and install the SP2 cd when I get it? Also I installed AVG Free Edition Antivirus. The Windows firewall is on and I have a Linksys router which I believe has a built in firewall of it's own. Do you think I am putting myself at risk not having another Firewall to go with the AVG antivirus?
