SEATTLE (Reuters) - Microsoft Corp said on Wednesday the upcoming Windows 10 operating system will be offered as a free upgrade to users of the most recent versions of Windows and Windows Phone software.
The announcement by Terry Myerson, who runs Microsoft's operating systems group, is a marked change for the company, which has charged for new versions of Windows, one of the main profit drivers.
Windows 10, expected on the market this autumn, will be available for one year as a free upgrade to users of Windows 7, Windows 8.1 and Windows Phone 8.1, Myerson said.
The shift shows Microsoft is moving toward a frequently updated, subscription model for its flagship operating system, rather than major, paid-for upgrades every few years.
