Not using Windows 8 I do not know if Windows Live Mail comes pre installed, but if not, have a look here http://www.filehippo.com/downloadwindowslive_mail/ Outlook Express is no more and I do not think it compatible with Win 8. On the same link above, Thunderbird is also a good email client. Also think about Google Mail ( Google it ! ). If your frien uses his Intyernet Provider email, this can be set up in Live Mail or Google mail ( I think) Others may be able to help more on this point.
