I have an acer laptop .Aspire 5100. It has Windows xp.. Acer gives you a program with it to take your computer back to when it was as if you just bought it. I was wondering if anyone has used that option. I have and it deleted everything on the laptop except for the operating system. That is what I wanted but how do I make sure that none of the things I don't want on there is in fact off of there?? I do know that at some point it had to me that it will overwrite on there and also there is now a second partition. how do I know that it is not in fact in the first partition??
