Windows 10 will be officially released in July this year. From the feedback information released by Microsoft, the media is generally optimistic about the prospects of Win 10. This article refers to the address: http://www.eepw.com.cn/article/273510.htm Microsoft announced that Windows users will be free to upgrade, Microsoft hopes to use the free to stimulate existing Windows users to upgrade as soon as possible, in order to achieve the rapid popularity of Win 10, According to Microsoft, there will be one billion users worldwide to upgrade Win 10. The biggest change in Windows 10 is the launch of the Universal APP Platform. In the future, consumers will use the same APP Store for mobile phones, tablets and computers. It has been rumored that Apple will unify iOS and Macintosh OS operating system platform, Microsoft is ahead of this time, Microsoft not only unified the operating system platform of mobile phones, tablets and computers, and even promoted to XBOX, Hololens and future IoT devices, Microsoft launched a free upgrade plan, The first step is of course to realize the rapid popularization of Win 10 as soon as possible. The second and final goal is to promote developers to port applications on Win 10 with a large number of user bases. In order to improve the ecology of Win 10 phones, Microsoft will even launch a migration. Tools to encourage Android and iOS developers to migrate apps to the Win 10 platform as soon as possible. At the beginning of the Surface tablet, Microsoft launched Surface RT for the ARM platform. Unfortunately, Surface RT performance is too poor. On the other hand, because many applications are not compatible with the X86 version of Surface, the Surface RT sales are very poor. Have to withdraw from the market, this Win 10 also supports the ARM platform, through the Universal APP Platform to solve the problem of application incompatibility, but may face the overall ecological problems of Win 10, of course, the best solution through free upgrade. Fortunately, the Win 10 release, the mainland industry is not as a spectator as usual, as the only flat-panel processor partner in the first phase, Fuzhou Ruixin Micro will launch the ARM processor tablet based on Win 10 for the first time. However, compared to the Win 10 computer version will be released in July, Win 10 ARM version is estimated to be delayed for some time, probably in August and September. Microsoft's launch of the Win 10 free upgrade program has had a certain impact on Microsoft's short-term revenue. However, because the fees for newly listed computers are still charged, the tablet chips for 9-inch and above are also charged. The overall impact should not be as big as expected. On the contrary, because the win 10 free upgrade can bring a large number of users in the short term, it can stimulate the enthusiasm of computer manufacturers to preset Win 10. The Win 10 launch is relatively good for the Lumia mobile phone, but it is still difficult to make an accurate judgment on how much the Lumia mobile phone is promoted. From the news released by the Microsoft conference, the Win 10 mobile phone can be changed after connecting the monitor and the mouse keyboard through the Continuum function. As a computer, for the average consumer, you don't have to buy a computer in the future. The general application can use the Lumia mobile phone as a computer host. This idea has been realized on Win 10 for many years, although this application will reduce the sales of the computer. However, the increase in sales of Win 10 phones is obviously not bad for Microsoft. Microsoft's launch of the Universal APP program stems from the gradual popularization of the cloud application market, including Office 365 in the past two years. As the largest platform upgrade in Microsoft history, the risk of Win 10 is not small, although Win 10 will launch a free upgrade plan. Is it really unknown that Microsoft is willing to promote more than one billion users in a short period of time? After all, not every consumer is willing to try some strange new operating system, which has been the highest in Windows XP over the years. Proof, of course, for Microsoft, which is in transition, this approach is worthwhile and must be done. I hope Microsoft will do so.
