Analysts believe Microsoft will make Windows 10 freemium for the world

Microsoft plans to show off its Windows 10 operating system to the consumer world in January, while analysts believe it should be made available in a freemium format. There were previous rumors that Microsoft could introduce a "Windows as a Service" cloud-based, subscription service, which would be a significant shift in tactics.

If Microsoft plans to have Windows 10 run on billions of devices, then providing a freemium approach could be a lucrative option. It's possible Microsoft could offer Windows 10 free for end-users, and provide features and services based on a subscription fee.

"Microsoft is the only company who still builds a significant business selling an operating system," said Steve Kleynhans, Gartner VP. "Today, consumers see the OS as part of the device and don't really distinguish it as a component to be paid for separately."
