Despite the recent speculation that Microsoft would make Windows free across the board, the company's future plans seems to be diffferent. "We've not had any conversations about Windows 10 being a loss leader for us," Kevin Turner, Microsoft's chief operating officer, said at a technology conference sponsored by Credit Suisse on Thursday. "But we've got to monetize it differently. There are additional opportunities for us to bring additional services to the product and do it in a creative way."

Turner added that new business models would allow the company "to monetize the lifetime of that customer" by selling them services and what he called "add-ons."

Microsoft already gives away its Windows Phone OS and Windows 8.1 for devices with small devices.

"You're seeing $200 laptops, you're seeing $99 Windows tablets, embracing and extending the ecosystem by lighting up some of these new business-model scenarios, allowing us to monetize the lifetime of that customer through services and different add-ons." Turner said.

More information on how Microsoft plans to increase its revenue from Windows will be forthcoming soon. "The business model stuff will be out in probably the early part of 2015," Turner said.
