The key trait of each item is the main reason for its preference: for the software industry, it is the essential high-performance and advanced technology that allows users to send their hard-earned money to software vendors, just to enhance the experience.
For Windows, it does have some version of this killer character. Windows 3.1 is a killer version because it makes the computer break the 640KB memory limit. Windows NT is a killer version because it introduces the concept of a C/S (client/server) architecture and introduces hardware-based memory protection in the environment.
WindowsXP because it is among individual users (Windows9x) and corporate users (WindowsNT) erected a bridge, becomes a killer version. Although Windows Vista is not a killer version, it has played a role in driving Windows XP forward, which has shaken people's perception of the Windows model.
At this point, I can throw view: Windows7 is a killer version - but the reason you should not imagine that. Not because it fixes a lot of bugs in Windows Vista, nor because it contributes to the aesthetics of the interface.
not because it uses the latest UI design. Although I am a fan of Windows7's latest taskbar driver interface, I always think that this is just a "learning" concept of the Mac. The same is not because of the lightness of Windows 7 compared to Windows Vista - the test results show that running the same workload, the RAM usage of both is almost the same.
Windows7 killer most important characteristic is actually intelligence. In short, it is much better at using the available hardware resources than its predecessors, and it has a good performance even in the face of complex, multi-process, multi-threaded workloads. Assuming that you have the same number of processors, Windows 7 does better than Windows Vista and Windows XP. It tests on HPZ800 workstations with dual quad-core Xeons. The results show that the performance gap between them is large: in a multi-process workflow In testing, Windows 7 is about 250% faster than Windows XP.
This is the killer qualities of Windows7. This also means that as users invest more in computer hardware, by using Windows 7 as the operating system with these hardware, they can more exploit the potential of processors, memory and chipsets. That is to say, if you still stick to Windows XP, it seems to be due to its low-key and relatively stable performance, but in fact it is not wise.
passage of time, the status of the hardware and WindowsXP era is quite different. At the time, the multi-core processor was just a "concept". Windows XP is also designed for single-core processors. Multiple processors work occasionally on distributed workstations, but the level of intelligence is far less complex than the current one. Corei7 or Xeon55xx series processors. Currently, Windows 7 is the operating system that should match the smart processor. If Microsoft is looking for a promotional slogan for Windows 7, I can give a suggestion that Windows 7 is really smart.
