Officially, Microsoft has said that Windows 10--the company's next operating system--will launch .

Predecessor Windows 8, released in October 2012, was controversial in that it introduced a touch-focused tile design that was markedly different to Windows 7. Microsoft addressed these criticisms with frequent--and substantial updates--including Windows 8.1.

The company isn't starting over with Windows 10, but Microsoft appears to be taking a more traditional approach with the new OS.

"We believe that, together with the feedback you provide us, we can build a product that all of our customers will love," Windows executive Terry Myerson said last year. "It will be our most open collaborate OS projects ever."
