I have an existing computer with Windows Vista Home Premium Edition. I have files on this computer I want to share with a new Windows 8 computer that I have not bought yet. My question is, do I need to buy a Windows 8 or Windows 8 Pro computer. Also, if I have files to share that are on a Windows Vista Home Premium computer, can I share them with a Windows 8 computer? I will not have a domain, just want to share one folder across a home network. If someone could help me out I'd appreciate it.
