Hey guys, i recently got windows vista and i currently have windows xp home on my laptop. i was reading some instructions but wasn't to entirely sure. It says i can: "Upgrading Windows when you already have a version of Windows on your computer and you want to keep your files, settings, and programs." Does that mean i can install windows vista without deleting anything or lose any of my old files? sounds a little to good to be true. usually u have to go through the process of deleting your whole hard drive don't you?
