IT'S OFFICIAL. Even Microsoft is counting down until they stop supporting Windows XP, Office 2003, and Exchange 2003. https://readytogo.microsoft.com/en-us/Pages/timeforchange/default.aspx
I finally moved my parents off XP and into Windows 8.1. I disabled the start screen and set everything up pretty much exactly the way it was with the old OS in terms of web browsers, desktop icons, etc. The only other upgrade was to Office 2013 (they were still running 2000), which they have had no problems using.
