Microsoft spent much of 2013 and 2014 correcting the mistakes of Windows 8 via a set of small but meaningful updates. But its best work was yet to come: the software giant would celebrate the 30th anniversary of its core desktop platform in 2015 with a new version, Windows 10, that would go on to be its longest-running and most successful yet.
Codenamed “Threshold,” Windows 10 was an explicit admission that Windows 8 was the wrong direction. Where Steven Sinofsky’s insular and divisive team had taken a bold but misguided bet on touch-first mobile interfaces, Terry Myerson set out to dismantle those mistakes as much as possible. Windows 10 would be desktop-focused, not touch-focused, and while traces of the touch-first mobile interfaces of the past were present, they were clearly secondary.
