After the release of Windows 8, Microsoft is actively working on its successor, code-named Windows Blue.
The new version of the operating system will extend the battery life for mobile computers based on Haswell processors, whose debut is also expected in early summer. It is reported that over the adaptive mechanisms of energy saving Intel and Microsoft are working together.
As you know, in the development of Haswell architecture, Intel did not focus on the improvement of computational performance, but to achieve energy efficiency.
