Hi, everyone. Wondering (esp. since I'm a Mac guy)... how do I prepare the XPS 13 w/ W10 to give to someone? My brother-in-law needs a computer and since my XPS 13 has been sitting around not getting much use, I figured I should give it to him. Before I do so, however, I'd like to freshly install W10 and all the accompanying trimmings. Not sure how to go about doing so. I upgraded from W8.1 to W10 utilizing the free update option. Would very much appreciate help on this. Thank you.
