I'm talking about this one research project:but MS closed it in 2008. I've read many articles about it, about high perfomance (30+% faster against tradinional monolithic kernels), much more secure etc. So it should be really a revolution in OS designing. Why they did it? I would be really happy if they didn't... So only one question i have: why? Was effective managers who destroyed it or some else? I'm thinging about it for many strenuous months...
Microsoft Singularity : why closed

First you need to understand the goals of Microsoft Research.Our labs are unique among corporate research facilities in that they  balance an open academic model with an effective process for building  research results into product development. This approach, unique among  corporate research facilities, pays off for Microsoft as enhancements  to virtually every product and service it offers and as entirely new  lines of business for the company. At the same time, it produces  significant technological and intellectual advances across the  spectrum of computer science.from: Inventing the Future of ComputingSecond you need to see how these ideas are translated into current projects.Windows 7. The latest version of Microsofts flagship operating system  incorporates a number of under the hood technologies from Microsoft  Research that contribute to the products improved performance,  reliability and usability. These include enhancements to handwriting  recognition, graphics performance, networking and security.  Additionally, the product development team made use of a number of  Microsoft Research technologies to write and test code efficiently and  more thoroughly identify potential security issues.See: Bringing Innovations to Life and Making Computers More Capable and UsefulLastly you need to understand that Singularity has been used as a springboard for other projects:Microsoft describes Singularity as a research project which  demonstrated that modern programming languages and software  engineering techniques could fundamentally improve software  architectures. Singularity ended up spawning and/or influencing a  number of other operating system research projects at Microsoft,  including Barrelfish, Helios, Midori (Wikipedia) and Drawbridge.from The father of Microsoft's Singularity OS moves on
