”We want to move from people needing Windows to choosing Windows, to loving Windows. That is our bold goal,” said Microsoft CEO Satya Nadella three years ago. At the time, Microsoft was unveiling more details about Windows 10, and surprising people with technologies like the HoloLens headset. It was an exciting time of opportunity and optimism that had Microsoft betting on people loving Windows so much that Windows 10 would be running on 1 billion devices within three years. Neither wager worked out — which is fine, because Windows as we know it is no longer critical to Microsoft’s future success.
