My Hotmail is threading all related email into one place, and thus combining different chains and no longer keeping separate or chronological messages. 

I fear I may have converted to "Windows Live Mail" as my address bar starts like this https://bay147.mail.live.com/default.aspx?n= . 

I am desperate to learn how to return to "regular" Hotmail, and wonder if this problem was created when I temporarily accepted an invitation to change to the new "outlook" format in Hotmail.  Any advice welcomed!
