A lot of news lately about the end of life for Windows XP. Certainly, there are plenty of corporate users out there still on this operating system. That's why its end of life has been extended so many times in the past.
The natural upgrade would be to the latest and greatest Microsoft operating system, Windows 8.1. But let's face it, not everyone is keen on Metro and therefore are considering a step-wise upgrade to Windows 7. As you plan your upgrades, you may want to take a look at this page from Microsoft. Microsoft maps out their intended end of mainstream support and end of extended support for each of their operating systems.
To summarize, moving to Windows 7 from XP may not be the best choice. You may want to invest in learning Windows 8.1 because Windows 7 goes off mainstream support on January 13, 2015. That's right around the corner. There is no guarantee that Microsoft will opt to extend support for Windows 7 like it has for Windows XP. (Extended support of Windows 7 is scheduled to end January 14, 2020.) On the plus side, I wonder if Microsoft will be releasing Service Pack 2 for Windows 7 on January 13th. Seems like a lucky day to install an OS update.
