Turner, in his keynote address to over 14,000 Microsoft partners, vendors and resellers here yesterday, said Windows 10 was the greatest operating system the company had released.
"It's the greatest release of Windows we've ever done," Turner said.
"This (Windows 10) will be the last monolithic release that we have that was built around the three year upgrade cycle. It is going to be about Windows as a Service," he said at the Microsoft Worldwide Partner Conference.

"The ability to keep a customer current with the latest technology has always been our Achilles' (heel) with Windows," Turner said. "We're fixing that with Windows 10," the company's Chief Operating Officer said.
