the fact is that Microsoft has changed the manufacturing process of operating systems.
If before the creation of the system took 2.5 years after the release of Windows 7, Microsoft realized that actually lags the market of operating systems and the latest trends .....
Google's aggressive promotion of its portable platform Android has forced Microsoft to revise cycles of creation - to upgrade their systems. It should also take into account that the company APPLE yearly releases updates for operating systems with the introduction of the new features.
So, Microsoft will no longer issue in the usual form of the so-called service pack (Service Pack) are only correct errors without introducing new features and functions!
In place of service pack (Service Pack) comes the so-called extended support system, ie, with patches of holes will be introduced and new features!
Creation time - release of these packages also reduced to one year. Ie, the first official release of the service pack to Microsoft Windows 8 should be expected in the fall, and in the summer it will be available to partners.
Frankly, all these attempts corporation can not save the situation, Microsoft is losing ground on all fronts ...
