After becoming stuck by a snowstorm in
Ithaca during a recruiting visit to his alma mater Cornell University in 1994, Sinofsky noticed that both faculty and students at the university were widely using the newly adopted internet to communicate and study. This was a dramatic change from his time at Cornell that relied on the mainframe program CUInfo for information access. He summarized his excitement in an email and memo, "Cornell Is Wired!" which he distributed, encouraging Gates to take the emerging

. Windows 7 proved to be a major success, with a rapidly growing user-base of over 450 million, and its launch contributed to record-breaking revenue earnings for Microsoft in 2010. Sinofsky and DeVaan blogged about the development process on the Engineering Windows 7 blog.
While at Windows, Sinofsky blogged extensively about the project's goals and the development process as a way to communicate with the over 4,000 person team and the rest of Microsoft,
ultimately publishing over 1,000 pages of blogs.
Sinofsky's philosophy on Windows 7 was to not make any promises about the product or even discuss anything about the product until Microsoft was sure that it felt like a quality product. This was a radical departure from Microsoft's typical way of handling in-development versions of Windows, which was to publicly share all plans and details about it early in the development cycle. Sinofsky also refrained from labeling versions of Windows "major" or "minor", and instead just called them releases. Sinofsky's leadership style influenced many other Microsoft divisions to follow his principles and practices on product development.
Sinofsky subsequently worked on Windows 8, which was intended to modernize Windows. Many of its design changes were meant to allow it to scale across PC and mobile interfaces in response to the rising popularity of touchscreen devices over PCs.
Among the most notable changes was the reinvention of Windows for the ARM processors then in use in the iPhone and later the iPad. This was widely viewed as both innovating and a challenge to the Microsoft-

partnership. During development, he regularly blogged about the feature set and the process of developing the new OS in his blog
Building Windows 8
A key element of the effort on ARM processors was the development of a Microsoft ARM-based computer to prove the potential. Sinofsky quietly created an internal team to develop the Surface computers, initially two models Surface RT and Surface Pro, for Nvidia ARM processor and Intel respectively.
Windows 8 launched to mixed reviews,
and was deemed a failure by commentators, including Sinofsky himself. However, he also expressed his belief that Windows 8 was simply "too much, too soon,"
and noting that "being early is the same as being wrong." Some aspects of Windows 8, including live tile menu interfaces and screen edge swiping, became standard components of mobile operating systems.
Sinofsky left Microsoft on December 31, 2012, after the failed launch of Windows 8.
His departure was described by both parties as a mutual decision,
but some news outlets speculated that it was the result of friction between himself and CEO

in November 2009.
The book discusses Sinofsky's struggle with refocusing the Windows Division after the Vista debacle, and the planning and development of the next major version of Windows that would come after Vista. Sinofsky talks about the focus of making a desirable high-quality product, while making no promises to the public, and shipping and delivering that product on time. The book was built around selected blog posts written by Sinofsky to communicate with the rest of the Microsoft team during the development of Windows 7. Sinofsky's personal insights and experiences recorded through the blog are interspersed with Iansiti's academic commentary on the challenges facing the team.
It was well received by critics. Lisa Oliva wrote that it "provided a great balance between theoretical and practical explanations" in a review for the ''Journal of Applied Management and Entrepreneurship''.
Hardcore Software
In 2020, it was announced that Sinofsky was writing ''Hardcore Software: Inside the Rise and Fall of the PC Revolution'', a first-person account of the PC told through the projects Sinofsky worked on and the competitive and technology landscape at the time. It focuses on the company's history between the 1980s and the 2010s, as it transitioned from the
