Microsoft takes the wraps off Windows 10

Microsoft has finally announced its new OS. The Wi-Fi password at today’s intimate San Francisco event was “Windows 2015”, leading some to speculate that Microsoft might have chosen to return to naming its OS after the year of launch (a nod to Windows 95/98), but that turned out not to be the case — a wise move. So what name would the tech giant choose? Not Windows 9, the obvious and expected pick, nor Windows One, the rumored alternative.
