Q If I don’t upgrade, will my PC running Windows 7/ Vista become obsolete and unusable?
A No. Windows 7 or Windows Vista will not be abandoned totally or will become defunct. According to the latest statistics, 44.71 per cent of computers still run on Windows 7, and a further 39.82 on the even older Windows XP. So if you don’t upgrade to Windows 8, your computer will still work fine, and you will still get software that runs on it.

Q I am very happy with Windows 7. What will I miss if I don’t upgrade to Windows 8?
A Most of the world is still using Windows 7. Windows 8, however, gives you a smoother, faster and intuitive interface. So you will have live tiles on your desktop which refresh with new information, support for gestures and much faster operation in terms of starting up and shutting down. This, we reckon, is the most radical change we have seen being made to Windows for a while.
