I just reformatted and did a clean install of Windows XP. Works great. But now of course, PcCillin is telling me to update windows. I understand that most of the updates are about Internet Explorer (fixing their vulnerabilities). Popup blockers were a problem for me in the past. They messed up everything--even when I turned them off in Explorer. Would it be a better option to NOT update Windows XP and just use Mozilla or something? Thanks.
