I hope this is the right forum for this. I am using a windows Vista machine given to me by a friend. They had previously installed iTunes on it and had made multiple purchases at the iTunes store. Well, I want to sync my iPhone 5S to the computer, but it wants me to put all my friend's stuff on my phone. My phone, for one thing, couldn't handle all that, even if, for a second thing, I wanted all that on my phone. So, my question is this: do I have to uninstall iTunes and do a completely new installation? If so, how do I make sure my friend's old stuff is gone and won't try to sync on to my phone. Thanks in advance.
