In that case why any user(Genuine Licensed holder of Windows OS)would wait for 2nd year?????????????????
its a marketing strategy by Microsoft imho
they will lure more people to upgrade from Windows 7 or even XP -- two versions of windows which people refuse to upgrade from
that way,once everyones on a Windows 8+ OS,itll be easier to manage windows updates etc and will eliminate people from switching to Chrome OS or even Mac OSX since windows has been having radical changes since Windows 8 and not everyone is liking it(I get why people dont like the interface on a non-touch but I dont get why people dont see how much better the OS is over even Windows 7)
