First time this has happened, I used my original XP x64 SP1 CD, slipped SP2 into it and used the same type of tweaks I use everytime, removing useless components such as briefcase, Outlook, and the like. After I installed it, all I had on the computer was Paint, secruty Center, Notepad and communication manager.... All the rest we're gone, I don't understand what happened. No internet explorer, nothing. How can I tell what went wrong
