VC ++ notes-Windows Development History

Windows origins can be traced back to work done by Xerox. In 1970, Xerox set up the famous research institution Palo Alto Research Center (PARC), which is engaged in the research of LAN, laser printer, graphic user interface and object-oriented technology, and announced the launch of the world's first commercial gui (graphical user interface) system in 1981: Star 8010 workstation. However, like many companies later, the technical advancement for various reasons did not bring it the expected commercial success.

At that time, Steve Jobs, one of the founders of Apple Computer, learned the importance of graphic user interfaces and broad market prospects after visiting the PARC research center of Xerox, he started to research and develop his own GUI system, and developed the first GUI system, Apple Lisa, in 1983. Soon afterwards, Apple launched its second GUI system, Apple Macintosh, which is the world's first successful commercial GUI system. At that time, apple only developed a GUI system on its PC for the sake of its marketing strategy when developing the Macintosh.
The IBM compatible microcomputer with the x86 microprocessor chip has been gradually exposed. In this way, Microsoft has provided development space and market for developing windows.

Microsoft has long been aware of the importance of building industry standards. In the spring of 1983, Microsoft announced the start of Research and Development of windows, hoping that it will become a standard GUI Operating System Based on Intel x86 microprocessor chip computers. It launched windows 1.03 and windows in and respectively. However, due to the current hardware and DOS Operating System Restrictions, these two versions were not very successful. Since then, Microsoft has made significant improvements to the Windows Memory Management and GUI, making the GUI more beautiful and supports Virtual Memory. Microsoft launched windows in and shot red. Once the operating system was launched, it achieved amazing commercial success: Microsoft sold 0.5 million copies of windows in less than six weeks, it broke the 6-week sales record of any software product, thus setting Microsoft's monopoly on the operating system.

Windows 3.0 was improved a year later by introducing the TrueType font technology, a scalable font technology that improves performance; A new file management design is introduced.ProgramTo improve the system reliability. More importantly, we have added support for object link Embedding (OLE) and multimedia technologies. Both windows3.0 and windows3.1 must run on the ms dos operating system.

Later, Microsoft launched the next-generation operating system Windows 95 (also known as Chicago) in 1995 by taking advantage of Windows Dongfeng, which can run independently without dos support. Windows 95 is a milestone in the development history of the operating system. It has made many significant improvements to Windows, including better and object-oriented graphic user interfaces, this reduces the user's learning burden. The 32-bit high-performance preemptive multi-task and multi-thread features provide built-in Internet support; more advanced multimedia support (sound, graphics, images, and so on) can be used to directly write screens and provide excellent support for games. plug-and-play allows users to easily configure hardware operations, it also avoids hardware conflicts, 32-bit linear addressing memory management, and good downward compatibility. Windows we mentioned later generally refer to Windows 95.
