windows 7 does NOT come with an email program.
(1) You can down load windows live - Good ole uSoft replacement for XP OE Express and Vista win mail (I use "good" very loosely and I do not use!)
(2) You can down load thunderbird (That seems quit popular here)
(3) You can install Outlook - Need a microsft Office product (This is what I use on Win 7 64 Bit)
(4) MY FAVORITE, You can copy your windows Vista Mail directory into win 7 and use vista windows mail (this is what I did for My wife's I3-540 32 bit Win 7) There is MORE to it than just copy. You have to get admin privilage (mispelled) on vista files, and on win 7 you also need privilage to rename win mail directory to old win mail. (Shi*(^^$& , just goole using vista win mail in windows 7.
