— Gabriel Aul (@GabeAul) December 4, 2014 Although, the answer is not final, most of the time, Microsoft doesn’t comment to questions if they don’t already know the plan. As such we can clearly assume the company will offer an upgrade path from Preview to the final version of Windows 10 when it launches.
