Microsoft Continues to Prototype non-Windows OSes

Last Updated on Monday, 17 August 2009 11:34 Written by Mire_B Monday, 17 August 2009 11:34

Microsoft continues to prototype non-Windows operating systems. Singularity and Midori are Microsoft Research projects exploring architectures beyond the good old Windows. Both platforms are non-Windows operating systems written in managed code. Singularity is already available for download, and Midori was in incubation in the first half of 2008.

From the company: Singularity is a research project focused on the construction of dependable systems through innovation in the areas of systems, languages, and tools. We are building a research operating system prototype (called Singularity), extending programming languages, and developing new techniques and tools for specifying and verifying program behavior.

Midori details are extremely scarce. The project, related to Singularity, generated a few headlines in 2008 with Mary Jo Foley having dug it up and SDTimes getting hold of inside documentation. But then Midori slipped out of sight, and interest died out with no additional information available to fuel the non-Windows fire.

You know what they say about slipping out of sight… So I thought I’d provide a reminder, especially since Microsoft is hiring fresh blood for the Microsoft Research Operating Systems Group. Want a chance to work on cutting edge research like Singularity and Midori? Microsoft Research is looking for a Research Software Development Engineer in Redmond.

Windows 7 Support Lifecycle – January 13th 2015 – Mainstream Support Retired

Last Updated on Saturday, 15 August 2009 09:44 Written by Mire_B Saturday, 15 August 2009 09:44

Since Windows 7 has been released to manufacturing on July 22nd, 2009, it’s only fair to start talking about just how much the operating system will live. And the answer is at least six years. Microsoft has committed to support Windows 7 until January 2015. It will be on January 13th, 2015 that the company plans to discontinue Mainstream Support for Windows 7.


This means that as Windows 7 was released approximately three years after Windows Vista, it will also benefit from an additional three years of support, after support for Vista ends on April 10, 2012. But still, some Windows Vista editions will outlive Windows 7. Vista Enterprise is one example. Extended Support for Vista Enterprise will be retired on April 11, 2017.


Microsoft announced only the end date for Mainstream Support, and did not provide deadlines for the end of life of the Home Basic and Home Premium N SKUs. This could point to the fact that the January 13th, 2009 could be just a preliminary support lifecycle end date, and that additional information will be offered. Certainly select Windows 7 editions, hint: Enterprise, will also benefit from Extended Support.


Below are the dates at which mainstream support for all Windows 7 editions will end:

Windows 7 Enterprise – 1/13/2015           

Windows 7 Professional N – 1/13/2015  

Windows 7 Home Basic – no information offered

Windows 7 Home Premium – 1/13/2015

Windows 7 Home Premium N – no information offered

Windows 7 Professional – 1/13/2015       

Windows 7 Starter – 1/13/2015  

Windows 7 Starter N – 1/13/2015             

Windows 7 Ultimate – 1/13/2015              

Windows 7 Ultimate N – 1/13/2015
