It’s out July 29
Windows 10, Microsoft’s new operating system, launches July 29. The biggest difference between it and older versions of Windows? It’s a totally free upgrade — provided you have Windows already installed on your computer.
That’s a big change for Microsoft, which could traditionally count on big sales of its latest operating systems. It’s also a shift that’s emblematic of larger changes at the company under CEO Satya Nadella, who’s moving many of Microsoft’s software products to subscription-based sales models.
