Another added: "Microsoft needs to do some long overdue house cleaning across the board. First thing they need to do is get a UI Czar that does a better job than the stupid Metro 2D sesame street primary colour UX [user interface].
"Second, fire some senior leaders in the business teams as well. There are general managers and vice presidents in business and operations groups making over $1m (£600,000) per year. How can this company survive with that sort of burden? Why do we need to pay $1M+ (with benefits) to a vice president in finance, purchasing, customer service and IT? ... We are crazy keeping these dinosaurs on for 15+ years, especially these GMs and VPs from the 1990s. That's why we can't think modern."
Sinofsky joined Microsoft in July 1989 as a software design engineer straight from the University of Massachusetts, Amherst, where he earnt a master's degree in computer science. He was promoted to technical assistant to Microsoft co-founder Bill Gates within three years.
In 1999, he became senior vice president of the Office division, becoming senior vice president of Windows and Windows Live in 2006 with a brief to rescue the company from the Windows Vista debacle, before his promotion to president of the Windows division in 2009.
Sinofsky had also been responsible for the unified interface between the 8-series of Windows operating systems, which had been met with both praise and criticism – not least for the number of different incompatible versions running across different devices. Late last week, though, CEO Ballmer had expressed disappointment at sales of the Microsoft Surface device launched at the end of October.
Sinofsky's replacement, Larson-Green, has worked at Microsoft since 1993. She worked on, and led, a number of high-profile products at Microsoft, including the user experience for early versions of Internet Explorer and, according to Microsoft, "helped drive the thinking behind the refresh of the user experience for Microsoft Office" – the much-criticised "ribbon interface".
