If your current PC runs Windows 7, you can install Windows 8.1 over the top of the old system by using Microsoft’s online upgrade. Indeed, if you bought a new Windows 7 PC after June 1, 2012, you probably already have a $14.99 upgrade certificate in hand.
As long as your copy of Windows 7 bears a “genuine” product key, and you have a copy of that key handy, the whole process takes less than 30 minutes — much less if you have a fast Internet connection. (“Genuine” being a Microsoft term that means your copy of Windows has passed an online test and doesn’t appear to be fake.)
