Hi, Finally ordered the SP4 i5 256GB. It will arrived Feb 1. What do I need to do to get prepared? There is my first ever tablet so I don't want to mess it up. Please post what you did for your SP4? I am planning to do an update first. Then, I will make a backup copy of the disc. I don't know how yet. Is there a specific website for the surface to get update? What backup program comes with Win 1o? Is window defender good enough for anti-virus and internet security? What else do I need to aware of? Thanks in advance.
