What's wrong with XP's update software? I reinstalled XP Home today (twice), and I cannot get the update feature to work. I have installed the latest board drivers, and I downloaded service pack 3 via another machine and installed the update manually, but XP's built-in update software still will not function. I can only go so far by visiting Windows Update web site due to validation requirements, but at this point, I am not ready to activate XP until I am sure the OS is functioning as it should. I have no 3rd party software installed (no antivirus, etc.). Thanks. Edit: I have posted the update log in four parts below.
