A major feature of Windows8 is that it will support the chip architecture of ARM, which means that Microsoft will expand the mobile market with a more open attitude, and in a sense, it also shows that Microsoft is trying to integrate resources and comprehensively transform. Steve ballmer, CEO of Microsoft, said that Microsoft would take Windows8 as an opportunity to "reshape" every part of its software empire through cloud computing. Horizontally, Windows8 supports not only Intel x86 processors, but also ARM architecture processors. Due to the dominant position of ARM processor in the field of mobile intelligent terminals, it means that Windows8 will continue the advantages of Microsoft in the traditional PC field and will be better applied in all kinds of mobile intelligent terminal devices. Vertically, Windows8 is compatible with Windows7. On the basis of Windows7, the performance, security, privacy and system reliability are all improved. In the arm development training class, Fuzhou Zhuo Yue Education said that in recent years, the operating systems of mobile intelligent terminals represented by Apple's iOS and Google's Android have developed rapidly, attracting a lot of media spotlight, especially the rise of iPhone and iPad, which has won tens of millions of fans for Apple around the world and exerted invisible pressure on Microsoft's market position. On the other hand, the decline in global PC shipments has greatly affected the development of Microsoft. Not long ago, IDC, a market research company, released a survey report, which lowered the global PC shipment growth forecast from 4.2% to 2.8% in 20 1 1 year. This is the second time this year that IDC has lowered its PC shipment growth forecast. In the arm development training class, Fuzhou Zhuo Yue Education also showed the rise of competitors and the difficulties faced by its own development environment, forcing Microsoft to accelerate the pace of innovation and make changes. On the basis of continuing to cooperate with Intel, ARM is also included in the cooperation. For Microsoft, the most important point of this cooperation is to broaden its development space in the mobile market. From the perspective of the whole industry, the competition of mobile intelligent terminal operating system will be more intense. Apple iOS and Google Android will face a new competitive situation; Intel, Microsoft's old partner, lost the advantage of "monopolizing" Microsoft, and the uncertainty of future development increased; Cooperation makes ARM stand on the same starting line with Intel in a sense, which helps to give play to the advantages of low power consumption of ARM. ARM products can't run any Intel x86 applications, which makes the future competition between them full of variables. However, competition within the industry ultimately benefits consumers. This kind of cooperation means that the market competition will be more intense, and the more intense the competition, the greater the possibility that users will get "benefits" from it. The rise of a new generation of mobile intelligent terminals dwarfs traditional PCs. For Microsoft, if it sticks to the traditional PC market blindly, it will not only lose the opportunity to compete with Apple and Google in the tide of mobile Internet, but also fall into a Jedi with the sinking of traditional PC. It is better to let go than to be satisfied with the status quo. For Microsoft, the release of Windows8 is more likely to be a harbinger of its strategic adjustment. As a result, this "giant" who once focused on traditional PCs may put more energy into the field of mobile Internet. Sun Yongjie, a well-known IT commentator, believes that Windows8 supports not only PCs that are still the core areas of Microsoft, but also tablets and smartphones. Microsoft wants to break through the barriers of PC and post-PC era (tablet and smart phone) and occupy a place in the tablet and smart phone market.
