"Support for Office 2003 ended on April 8, 2014.
Microsoft quietly gave Office 2007 (with Service Pack 3) an extension. Instead of moving into the Extended Support phase on April 9, as was the original plan, Office 2007 now moves to Extended on October 9, 2012. Extended support for the product ends on October 10, 2017."
I still have WINDOWS XP-PRO up and going and am using MS OFFICE 2007.
I will most likely move to WINDOWS 7 PRO but of course it probably doesn't have a long lifespan as well. You can still purchase WIN 7 from places like AMAZON in plain wrappers but the local computer stores no longer have WIN 7 on the shelf in the MS Packages.
I just can't seem to move to the WIN 8 OS system as almost all of my programs will not work on it... Will be a big cost for me to move to WIN 8...
